  • Advantages and disadvantages of building a single page web application

    - by ryanzec
    I'm nearing the end of a prototyping/proof of concept phase for a side project I'm working on, and trying to decide on some larger scale application design decisions. The app is a project management system tailored more towards the agile development process. One of the decisions I need to make is whether or not to go with a traditional multi-page application or a single page application. Currently my prototype is a traditional multi-page setup, however I have been looking at backbone.js to clean up and apply some structure to my Javascript (jQuery) code. It seems like while backbone.js can be used in multi-page applications, it shines more with single page applications. I am trying to come up with a list of advantages and disadvantages of using a single page application design approach. So far I have: Advantages All data has to be available via some sort of API - this is a big advantage for my use case as I want to have an API to my application anyway. Right now about 60-70% of my calls to get/update data are done through a REST API. Doing a single page application will allow me to better test my REST API since the application itself will use it. It also means that as the application grows, the API itself will grow since that is what the application uses; no need to maintain the API as an add-on to the application. More responsive application - since all data loaded after the initial page is kept to a minimum and transmitted in a compact format (like JSON), data requests should generally be faster, and the server will do slightly less processing. Disadvantages Duplication of code - for example, model code. I am going to have to create models both on the server side (PHP in this case) and the client side in Javascript. Business logic in Javascript - I can't give any concrete examples on why this would be bad but it just doesn't feel right to me having business logic in Javascript that anyone can read. Javascript memory leaks - since the page never reloads, Javascript memory leaks can happen, and I would not even know where to begin to debug them. There are also other things that are kind of double edged swords. For example, with single page applications, the data processed for each request can be a lot less since the application will be asking for the minimum data it needs for the particular request, however it also means that there could be a lot more small request to the server. I'm not sure if that is a good or bad thing. What are some of the advantages and disadvantages of single page web applications that I should keep in mind when deciding which way I should go for my project?

  • Need to replace HTML single-quote entity in MySQL

    - by modulaaron
    Hi, I currently have the following MySQL statement to replace the HTML entity for a single quote with an actual single quote: update photo_galleries replace(title, '&#39;', '\''); This statement returns an error. I have tried adding additional backslashes, but this does not help at all. I want to run this command using pure SQL (no PHP, etc.). Any suggestions are welcome and appreciated. Thanks.

  • OSB 11g & SAP – Single Channel/Program ID for Multiple IDOCs

    - by Shub Lahiri, A-Team
    Background This note is a supplement to the blog entry, SOA 11g & SAP – Single Channel/Program ID for Multiple IDOCs by Greg Mally. Greg has shown how a single SOA Suite composite can be used with iWay Adapters to receive multiple IDOC types via a single channel in the adapter, corresponding to a single programID on the SAP system. We will try to address the same requirements within the OSB framework here. Project Built - Design Time The basic build of an OSB project with iWay SAP Adapter, as seen in another entry in this blog, consists of working in OSB Design console and Application Explorer. OSB Design Time - Part 1 We will create a placeholder project first in OSB with a proper directory structure, so that we can export the WSDL, XSD and the JCA binding information from Application Explorer directly into this project. Application Explorer - iWay Design Time Tool Receiving IDOCs is classified as an inbound event within Application Explorer. For setting up events, a channel is first defined (e.g. iDoc_Channel) using the same PROGRAMID (RFC destination), as defined within SAP for the OSB server. Next, the same channel is used to export the JCA Inbound Event artifacts for the candidate IDOC, e.g. DEBMAS06 directly to the pre-created OSB project. Note that the validation for schema has been turned off. As a result, this will allow the adapter, at runtime, to use a single channel to receive multiple IDOC types from SAP and pass them on to the OSB runtime engine without any validation. In other words, we do not have to repeat the above step for each IDOC type. OSB Design Time - Part 2 Create 2 simple XML based Business Services to write to a file, e.g.  SAP_DEBMAS_File and SAP_MATMAS_File. Next, generate a Proxy Service using the JCA binding file exported from Application Explorer in the previous section. In the generated proxy service, edit the message flow and add a route node. Add a routing table in the route node with the following routing function. fn:local-name-from-QName(fn:node-name($body/*[1])) This function takes advantage of the fact that the XML payload at runtime, after translation by adapter, has the IDOC type as the top element. With the routing function in place, build the routing table to add 2 branches to route the IDOCs to the appropriate Business Service for writing the XML payload to files in separate directories. This completes the build of the OSB project. Testing - Run-Time After deployment and activation, the SAP adapter will wait to receive multiple types of IDOCs sent from the SAP system using a single channel. Upon receipt of the IDOCs, the OSB project will route them appropriately to save the corresponding XML payloads for different IDOC types in different directories.

  • How to use ASP.NET Routing in a Quote of the Day Website

    - by SidC
    Good Afternoon, A client is interested in creating an ASP.NET 2.0 website whose purpose is to serve up a "quote of the day". He wants the quotes on static content pages all attached to the same master page. The quote pages must be viewed in a certain sequence, and site browsers cannot view any other pages than the starting page when browsing to the site. That is, everyone must go to page 001.aspx when entering the site. Two Questions: 1. The content pages are going to be created by the client using an excel data source and a merge process by which each quote page is created eg. 001.aspx, 002.aspx etc. This seems clunky to me at best. Would ASP.NET Dynamic Data be a better solution here? I'm new to ASP.NET Routing and URL Rewriting as a whole. How would I setup a route table to ensure that users always entered the site on the same entry page, and create a route table such that default.aspx resolves to 001.aspx? Thanks, Sid

  • Should these concerns be separated into separate objects?

    - by Lewis Bassett
    I have objects which implement the interface BroadcastInterface, which represents a message that is to be broadcast to all users of a particular group. It has a setter and getter method for the Subject and Body properties, and an addRecipientRole() method, which takes a given role and finds the contact token (e.g., an email address) for each user in the role and stores it. It then has a getContactTokens() method. BroadcastInterface objects are passed to an object that implements BroadcasterInterface. These objects are responsible for broadcasting a passed BroadcastInterface object. For example, an EmailBroadcaster implementation of the BroadcasterInterface will take EmailBroadcast objects and use the mailer services to email them out. Now, depending on what BroadcasterInterface implementation is used to broadcast, a different implementation of BroadcastInterface is used by client code. The Single Responsibility Principle seems to suggest that I should have a separate BroadcastFactory object, for creating BroadcastInterface objects, depending on what BroadcasterInterface implementation is used, as creating the BroadcastInterface object is a different responsibility to broadcasting them. But the class used for creating BroadcastInterface objects depends on what implementation of BroadcasterInterface is used to broadcast them. I think, because the knowledge of what method is used to send the broadcasts should only be configured once, the BroadcasterInterface object should be responsible for providing new BroadcastInterface objects. Does the responsibility of “creating and broadcasting objects that implement the BroadcastInterface interface” violate the Single Responsibility Principle? (Because the contact token for sending the broadcast out to the users will differ depending on the way it is broadcasted, I need different broadcast classes—though client code will not be able to tell the difference.)

  • Hosting several HTTP servers on single domain name

    - by Nakilon
    Several people have got a single domain name server.company.com server, where they are now supposed to host their infrastructure or temporal projects, written in different ways even in different programming languages. How do they divide the domain? Split into subdomains: john.server.company.com, kate.server.company.com, etc. This would need a lot of admins' assistance, time, etc. -- there would be no way for John and Kate to do it themselves. Split into url namespaces: server.company.com/john/, server.company.com/kate/, etc. Pro: They now can make a single welcome page at root with any additional info (if they need?) Con: Each server would need to know their namespace string constant, and hrefs like / whould need patching. Split into ports: server.company.com:8080, server.company.com:8081, etc. and make a single :80 welcome page. Pro: They still can make a single welcome page at :80 Con: ??? I would like to know more pros and cons for 2 and 3 solution.

  • Single complex or multiple simple autoload functions [on hold]

    - by Tyson of the Northwest
    Using the spl_autoload_register(), should I use a single autoload function that contains all the logic to determine where the include files are or should I break each include grouping into it's own function with it's own logic to include the files for the called function? As the places where include files may reside expands so too will the logic of a single function. If I break it into multiple functions I can add functions as new groupings are added, but the functions will be copy/pastes of each other with minor alterations. Currently I have a tool with a single registered autoload function that picks apart the class name and tries to predict where it is and then includes it. Due to naming conventions for the project this has been pretty simple. if has namespace if in template namespace look in Root\Templates else look in Root\Modules\Namespace else look in Root\System if file exists include But we are starting to include Interfaces and Traits into our codebase and it hurts me to include the type of a thing in it's name. So we are looking at instead of a single autoload function that digs through the class name and looks for the file and has increasingly complex logic to it, we are looking at having multiple autoload functions registered. But each one follows the same pattern and any time I see that I get paranoid about code copying. function systemAutoloadFunc logic to create probable filename if filename exists in system include it and return true else return false function moduleAutoloadFunc logic to create probable filename if filename exists in modules include it and return true else return false Every autoload function will follow that pattern and the last of each function if filename exists, include return true else return false is going to be identical code. This makes me paranoid about having to update it later across the board if the file_exists include pattern we are using ever changes. Or is it just that, paranoia and the multiple functions with some identical code is the best option?

  • Strange Google Maps v3 geocode behavior when a quote is in the address

    - by AlexV
    See my test page. When on the page, click the top left button "Geocode". If you are in Firefox, geocoder.geocode() will have it's status equal to ERROR (and pop an alert after a few seconds). In Internet Explorer (at least 7), everything is fine and the marker is added to the map. If you remove the quote from the address (l'Assomption -- lAssomption), everything execute fine in Firefox. Now with my question: how a quote can "crash" the Google Maps V3 API only in Firefox!?

  • match "//" comments with regex but not inside a quote

    - by Wireless102
    I need to match and replace some comments. for example: $test = "the url is http://www.google.com";// comment "<-- that quote needs to be matched I want to match the comments outside of the quotes, and replace any "'s in the comments with &quot;'s. I have tried a number of patterns and different ways of running them but with no luck. The regex will be run with javascript to match php "//" comments UPDATE: I took the regex from borkweb below and modified it. used a function from http://ejohn.org/blog/search-and-dont-replace/ and came up with this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript"> function t_replace(data){ var q = {}, ret = ""; data.replace(/(?:((["'\/]*(("[^"]*")|('[^']*'))?[\s]*)?[\/\/|#][^"|^']*))/g, function(value){ q[key] = value; }); for ( var key in q ){ ret = q[key]; } var text = data.split(ret); var out = ret + text[1]; out = out.replace(/"/g,"&quot;"); out = out.replace(/'/g,"&apos;"); return text[0] + out; } </script> </head> <body> <script type="text/javascript"> document.write(t_replace("$test = \"the url is http://www.google.com\";// c'o\"mment \"\"\"<-- that quote needs to be matched")+"<br>"); document.write(t_replace("$test = 'the url is http://www.google.com';# c'o\"mment \"\"\"<-- that quote needs to be matched")); </script> </body> </html> it handles all the line comments outside of single or double quotes. Is there anyway I could optimize this function?

  • It's not just “Single Sign-on” by Steve Knott (aurionPro SENA)

    - by Greg Jensen
    It is true that Oracle Enterprise Single Sign-on (Oracle ESSO) started out as purely an application single sign-on tool but as we have seen in the previous articles in this series the product has matured into a suite of tools that can do more than just automated single sign-on and can also provide rapidly deployed, cost effective solution to many demanding password management problems. In the last article of this series I would like to discuss three cases where customers faced password scenarios that required more than just single sign-on and how some of the less well known tools in the Oracle ESSO suite “kitbag” helped solve these challenges. Case #1 One of the issues often faced by our customers is how to keep their applications compliant. I had a client who liked the idea of automated single sign-on for most of his applications but had a key requirement to actually increase the security for one specific SOX application. For the SOX application he wanted to secure access by using two-factor authentication with a smartcard. The problem was that the application did not support two-factor authentication. The solution was to use a feature from the Oracle ESSO suite called authentication manager. This feature enables you to have multiple authentication methods for the same user which in this case was a smartcard and the Windows password.  Within authentication manager each authenticator can be configured with a security grade so we gave the smartcard a high grade and the Windows password a normal grade. Security grading in Oracle ESSO can be configured on a per application basis so we set the SOX application to require the higher grade smartcard authenticator. The end result for the user was that they enjoyed automated single sign-on for most of the applications apart from the SOX application. When the SOX application was launched, the user was required by ESSO to present their smartcard before being given access to the application. Case #2 Another example solving compliance issues was in the case of a large energy company who had a number of core billing applications. New regulations required that users change their password regularly and use a complex password. The problem facing the customer was that the core billing applications did not have any native user password change functionality. The customer could not replace the core applications because of the cost and time required to re-develop them. With a reputation for innovation aurionPro SENA were approached to provide a solution to this problem using Oracle ESSO. Oracle ESSO has a password expiry feature that can be triggered periodically based on the timestamp of the users’ last password creation therefore our strategy here was to leverage this feature to provide the password change experience. The trigger can launch an application change password event however in this scenario there was no native change password feature that could be launched therefore a “dummy” change password screen was created that could imitate the missing change password function and connect to the application database on behalf of the user. Oracle ESSO was configured to trigger a change password event every 60 days. After this period if the user launched the application Oracle ESSO would detect the logon screen and invoke the password expiry feature. Oracle ESSO would trigger the “dummy screen,” detect it automatically as the application change password screen and insert a complex password on behalf of the user. After the password event had completed the user was logged on to the application with their new password. All this was provided at a fraction of the cost of re-developing the core applications. Case #3 Recent popular initiatives such as the BYOD and working from home schemes bring with them many challenges in administering “unmanaged machines” and sometimes “unmanageable users.” In a recent case, a client had a dispersed community of casual contractors who worked for the business using their own laptops to access applications. To improve security the around password management the security goal was to provision the passwords directly to these contractors. In a previous article we saw how Oracle ESSO has the capability to provision passwords through Provisioning Gateway but the challenge in this scenario was how to get the Oracle ESSO agent to the casual contractor on an unmanaged machine. The answer was to use another tool in the suite, Oracle ESSO Anywhere. This component can compile the normal Oracle ESSO functionality into a deployment package that can be made available from a website in a similar way to a streamed application. The ESSO Anywhere agent does not actually install into the registry or program files but runs in a folder within the user’s profile therefore no local administrator rights are required for installation. The ESSO Anywhere package can also be configured to stay persistent or disable itself at the end of the user’s session. In this case the user just needed to be told where the website package was located and download the package. Once the download was complete the agent started automatically and the user was provided with single sign-on to their applications without ever knowing the application passwords. Finally, as we have seen in these series Oracle ESSO not only has great utilities in its own tool box but also has direct integration with Oracle Privileged Account Manager, Oracle Identity Manager and Oracle Access Manager. Integrated together with these tools provides a complete and complementary platform to address even the most complex identity and access management requirements. So what next for Oracle ESSO? “Agentless ESSO available in the cloud” – but that will be a subject for a future Oracle ESSO series!

  • SQL SERVER – Single Wait Time Introduction with Simple Example – Wait Type – Day 2 of 28

    - by pinaldave
    In this post, let’s delve a bit more in depth regarding wait stats. The very first question: when do the wait stats occur? Here is the simple answer. When SQL Server is executing any task, and if for any reason it has to wait for resources to execute the task, this wait is recorded by SQL Server with the reason for the delay. Later on we can analyze these wait stats to understand the reason the task was delayed and maybe we can eliminate the wait for SQL Server. It is not always possible to remove the wait type 100%, but there are few suggestions that can help. Before we continue learning about wait types and wait stats, we need to understand three important milestones of the query life-cycle. Running - a query which is being executed on a CPU is called a running query. This query is responsible for CPU time. Runnable – a query which is ready to execute and waiting for its turn to run is called a runnable query. This query is responsible for Single Wait time. (In other words, the query is ready to run but CPU is servicing another query). Suspended – a query which is waiting due to any reason (to know the reason, we are learning wait stats) to be converted to runnable is suspended query. This query is responsible for wait time. (In other words, this is the time we are trying to reduce). In simple words, query execution time is a summation of the query Executing CPU Time (Running) + Query Wait Time (Suspended) + Query Single Wait Time (Runnable). Again, it may be possible a query goes to all these stats multiple times. Let us try to understand the whole thing with a simple analogy of a taxi and a passenger. Two friends, Tom and Danny, go to the mall together. When they leave the mall, they decide to take a taxi. Tom and Danny both stand in the line waiting for their turn to get into the taxi. This is the Signal Wait Time as they are ready to get into the taxi but the taxis are currently serving other customer and they have to wait for their turn. In other word they are in a runnable state. Now when it is their turn to get into the taxi, the taxi driver informs them he does not take credit cards and only cash is accepted. Neither Tom nor Danny have enough cash, they both cannot get into the vehicle. Tom waits outside in the queue and Danny goes to ATM to fetch the cash. During this time the taxi cannot wait, they have to let other passengers get into the taxi. As Tom and Danny both are outside in the queue, this is the Query Wait Time and they are in the suspended state. They cannot do anything till they get the cash. Once Danny gets the cash, they are both standing in the line again, creating one more Single Wait Time. This time when their turn comes they can pay the taxi driver in cash and reach their destination. The time taken for the taxi to get from the mall to the destination is running time (CPU time) and the taxi is running. I hope this analogy is bit clear with the wait stats. You can check the single wait stats using following query of Glenn Berry. -- Signal Waits for instance SELECT CAST(100.0 * SUM(signal_wait_time_ms) / SUM (wait_time_ms) AS NUMERIC(20,2)) AS [%signal (cpu) waits], CAST(100.0 * SUM(wait_time_ms - signal_wait_time_ms) / SUM (wait_time_ms) AS NUMERIC(20,2)) AS [%resource waits] FROM sys.dm_os_wait_stats OPTION (RECOMPILE); Higher the single wait stats are not good for the system. Very high value indicates CPU pressure. In my experience, when systems are running smooth and without any glitch the single wait stat is lower than 20%. Again, this number can be debated (and it is from my experience and is not documented anywhere). In other words, lower is better and higher is not good for the system. In future articles we will discuss in detail the various wait types and wait stats and their resolution. Read all the post in the Wait Types and Queue series.

  • Solution with multiple projects and (GitHub) single issue tracker and repository

    - by Luiz Damim
    I have a Visual Studio solution with multiple projects: Acme.Core Acme.Core.Tests Acme.UI.MvcSite1 Acme.UI.MvcSite2 Acme.UI.WinformsApp1 Acme.UI.WinformsApp2 ... The entire solution is checked-in in a single GitHub (private) repo. Acme.Core contains our business logic and all UI projects are deployables. UI projects have different requirements and features, but some of them are implemented in more than one project. All issues are opened in a single issue tracker and classified using labels ([MvcSite1], [WinformsApp1], etc) but I'm thinking it's starting to get messy. Is it ok to use a single repository and issue tracker to track multiple projects in one solution?

  • Recommend an open source CMS for single page web site

    - by RedMan
    Hi I want to create a single page web site like http://kiskolabs.com/ or http://www.carat.se to display my portfolio. I want to add new products after launching the site without having to edit the entire site. I've looked at opencart (too much for single page site), Magneto (more for ecommerce), Wordpress (couldn't find open source / free templates which i can start from). Can you suggest a CMS which will support the creation of a single page site and allow insertion of new products without having to edit the entire page? I would prefer a CMS which also has open source / free templates which I can tweak for my use. I can do php and mysql, xml. If it is an easier option I can do PSD to site (but don't know much about this at all).

  • Single Sign On 802.1x Wireless - saying “Connecting to <SSID>”, hangs for 10 seconds, fails with “Unable to connect to <SSID>, Logging on…”.

    - by Phaedrus
    We are implementing WiFi on Windows 7 machines in our corporate environment. Machines should be able to log into the domain by WiFi as the Machine (Pre-Logon), and as the User (Post-Logon). We have everything working correctly except for 2 things: 1) Sometimes the login scripts don't run 2) The user VLAN is sometimes different than the machine vlan, and no DHCP renew occurs after user logon. I am clear that both these problems should be fixable by using the "Single Sign On" Option under the 802.1x Wireless Vista GPO, and setting the wireless to connect immediately before user logon and also by enabling "This network uses different VLAN for authentication with machine and user credentials" If I enable these GPO settings in a lab, the computer does authenticate & gets WIFI before the user logs on, so when the login box is displayed, it says “Windows will try to connect to ”, even though it is already connected (which should be ok?). Enter the user credentials and it goes to a screen saying “Connecting to ”, hangs for 10 seconds, fails with “Unable to connect to , Logging on…”. Desktop fires up and then the user re-authenticates with no problem as himself instead of the machine, but by that point, we defeat the point of the WiFi SSO “before user logon”. Also by that point, no DHCP renew seems to occur, and the user is still stuck with the wrong IP address for the new VLAN. When the “Connecting to ” screen comes up, there’s no indication on the AP or the Radius server that anything whatsoever is happening after credentials are entered until after the domain logon. Also with this policy enabled, sometimes windows hangs on a black screen indefinitely until I disable the Wireless NIC, so something is knackered for sure. What have I missed? Suggestions are much appreciated... /P

    In my domain: Users have many Bills Bills have many BillItems (and therefore Users have many BillItems through Bills) Every BillItem is one of: Call SMS (text message) MMS (multimedia message) Data Here are the properties of each individual BillItem (some are common): My question is whether I should model this arrangement with single-table inheritance (i.e., one "bill_items" table with a "type" column) or polymorphism (separate tables for each BillItem type), and why.

  • Canonicalization of single, small pages like reviews or product categories [SEO]

    - by Valorized
    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/">HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do? Thank you for your help!

    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/"> HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do?
