  • How to block this URL pattern in Varnish VCL?

    - by iTech
    My website is getting badly hit by spambots and scrappers, I am using Cloudflare but the problem still remains there. The problem is spambots accessing non-existing urls causing a lot of load to my drupal backend which goes all the way and bootstraps db just to serve a 404 error doc. I cant simply dish out non-drupal 404's for all page not found errors, as I need to have drupal catch them. Since, varnish is in front it can check if the bot is acting nice and asking for valid url - if not it servers them a 404 or 403. These bots are causing errors using this pattern : http://www.megaleecher.net/http:/www.megaleecher.net/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_Storage Now, pls. suggest a regex varnbisg VCL directive which catches this URL pattern and serves a 404 error from varnish, preventing it from reaching apache/drupal ?

  • Why won't my styles show in a Dynamics CRM 4 IFRAME?

    - by Dan Crowther
    I have created a web page (ASP.NET) that includes a stylesheet to mimic Dynamics CRM styles. This is to be used in a CRM IFRAME (within a form). The stylesheet is referenced as follows: <head id="Head1" runat="server"> <link href="Styles.css" rel="stylesheet" type="text/css" /> </head> When I load the page in Visual Studio, all is well. When I load it in CRM, none of the styles are shown and no images are displayed. If I browse directly to the image, I get a 404 error. However, the pages function correctly. I have set read permissions for "Everyone" on the server to see if that was causing a problem but it didn't help. I also tried putting a plain HTML page in the folder and that won't load either - again a 404. The page is installed in the ISV folder ..../isv/MyProject. Can anyone help? EDIT This is on a multi-tenancy system. On my test company (testcompany) if I browse to http://crm/testcompany/isv/MyProject/MyPage.aspx, the page is loaded (without styles and images). If I browse to http://crm/testcompany/isv/MyProject/TestImage.gif, the image is not shown. If I browse to http://crm/isv/MyProject/TestImage.gif, the image is shown. Does this suggest a problem with the server setup and the way CRM messes around with virtual directories?

  • Can not find the "variables.tcl" file in Varnish Security

    - by Vladimir
    Varnish Security main.vcl contains # clear all internal variables include "/etc/varnish/security/build/variables.vcl"; and # fallthrough: clear all internal variables on security.vcl_recv exit include "/etc/varnish/security/build/variables.vcl"; but /etc/varnish/security/build/variables.vcl is not included into the git. I commented it out, and it is working fine but where can I get that file?

  • To synchronise css styles in a browser and on a server.

    - by kalininew
    Prompt, please: whether it is possible in general from a browser (for example using firebug in firefox) to edit css a file on a server? I heard that there is an addition to firefox for connection on FTP (FireFTP). It is possible to change styles on page in firebug. Whether it is impossible to "combine" them - you change css styles in firebug, and they varies on a server? Who can heard about such miracle (not necessarily for firefox, suddenly for chrome there is such piece).

  • Prototype setStyle not working in IE6.

    - by Smickie
    Hi, I'm using prototype and setStyle in IE6 is just messing everything up. It's throwing a big error. I've Googled it but cant find a solution. I've identified the line in prototype with the IE script debugger, it's the final else block: setStyle: function(element, styles) { element = $(element); var elementStyle = element.style, match; if (Object.isString(styles)) { element.style.cssText += ';' + styles; return styles.include('opacity') ? element.setOpacity(styles.match(/opacity:\s*(\d?\.?\d*)/)[1]) : element; } for (var property in styles) if (property == 'opacity') element.setOpacity(styles[property]); else elementStyle[(property == 'float' || property == 'cssFloat') ? (Object.isUndefined(elementStyle.styleFloat) ? 'cssFloat' : 'styleFloat') : property] = styles[property]; return element; }, Anyone had this problem? P.S. normally I would use jQuery however this is someone else code I've had to update.

  • Varnish does not recognize req.hash

    - by Yogesh
    I have Varnish 3.0.2 on Redhat and service varnish start fails after I added vcl_hash section. I did varnishd and then loaded the vcl using vcl.load vcl.load default default.vcl Message from VCC-compiler: Unknown variable 'req.hash' At: ('input' Line 24 Pos 9) set req.hash += req.url; --------########------------ Running VCC-compiler failed, exit 1 cat default.vcl backend default { .host = "127.0.0.1"; .port = "8080"; } sub vcl_recv { if( req.url ~ "\.(css|js|jpg|jpeg|png|swf|ico|gif|jsp)$" ) { unset req.http.cookie; } } sub vcl_hash { set req.hash += req.url; set req.hash += req.http.host; if( req.httpCookie == "JSESSIONID" ) { set req.http.X-Varnish-Hashed-On = regsub( req.http.Cookie, "^.*?JSESSIONID=([a-zA-z0-9]{32}\.[a-zA-Z0-9]+)([\s$\n])*.*?$", "\1" ); set req.hash += req.http.X-Varnish-Hashed-On; } return(hash); } What could be wrong?

  • How to deal with different programming styles in a team?

    - by user3287
    We have a small dev team (only 3 developers) and we recently got a new team member. While he is a smart coder, his coding style is completely different from ours. Our existing code base contains mostly readable, clean and maintainable code, but the new team member is quickly changing many files, introducing ugly hacks and shortcuts, using defines all over the place, adding functions in the wrong places, etc. My question is if others have experienced such a situation before, and if anyone has tips on how to talk to him.

  • Is there any way to lock down Photoshop to prevent designers from creating styles that cannot be rendered in CSS?

    - by Hugo Rodger-Brown
    Photoshop is a much more powerful design tool than CSS, and given free reign to design at will, designers will often tweak things like font settings to a degree that cannot be recreated on the web. Is there any way to lock down Photoshop, or perhaps run an equivalent of the Office 2010 "Compatability report" that shows the designer where they have designed something that cannot be rendered on a web page. Something like the old-school "web-safe" colour palette, but for an overall design.

  • Should we encourage coding styles in favor of developer's autonomy, or discourage it in favor of consistency?

    - by Saeed Neamati
    A developer writes if/else blocks with one-line code statements like: if (condition) // Do this one-line code else // Do this one-line code Another uses curly braces for all of them: if (condition) { // Do this one-line code } else { // Do this one-line code } A developer first instantiates an object, then uses it: HelperClass helper = new HelperClass(); helper.DoSomething(); Another developer instantiates and uses the object in one line: new HelperClass().DoSomething(); A developer is more easy with arrays, and for loops: string[] ordinals = new string[] {'First', 'Second', 'Third'}; for (i = 0; i < ordinals.Length; i++) { // Do something } Another writes: List<string> ordinals = new List<string>() {'First', 'Second', 'Third'}; foreach (string ordinal in ordinals) { // Do something } I'm sure that you know what I'm talking about. I call it coding style (cause I don't know what it's called). But whatever we call it, is it good or bad? Does encouraging it have an effect of higher productivity of developers? Should we ask developers to try to write code the way we tell them, so to make the whole system become style-consistent?

  • EE vs Computer Science: Effect on Developers' Approaches, Styles?

    - by DarenW
    Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

  • Firefox 11 affiche la structure des pages web en 3D et les changements dans les feuilles de styles CSS en temps réel

    Firefox 11 affiche la structure des pages web en 3D Et les changements dans les feuilles de style CSS en temps réel Firefox 11 vient d'intégrer un ensemble d'améliorations qui risquent de ne pas laisser les développeurs web indifférents. La première nouveauté est un outil qui permet de visualiser la structure (CSS, etc.) d'une page en 3D. Page Inspector 3D View, surnommé Tilt, repose sur WebGL. « Cet outil permet à tout utilisateur de comprendre immédiatement le lien entre le code et la page finale », explique Mozilla. « Alors que les outils pour développeurs, tels que « view source », ont toujours été utiles pour apprendre à développer une page, l'affichage en 3D...

  • Do any database "styles" use discrete files for their tables?

    - by Brad
    I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

  • Assorted list of what's new in Delphi [Language, RTL, VCL]?

    - by utku_karatas
    Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

  • Customizing UPK outputs (Part 1)

    - by [email protected]
    If you are familiar with Oracle's User Productivity Kit, you are aware that UPK is a great product for rapidly developing application training. Did you know that you can also customize the UPK outputs to incorporate your company's logo, colors, and preferred styles? There are several areas that support customization: Logo - Within the developer, you can change the logo for all outputs at one time. Player - The player output uses a style sheet that can be updated to change colors, graphics and other visual branding. Documentation - The print documentation uses a Word-based template that can be modified to match your corporate standards. I'll discuss the first one today, and we'll cover the others in subsequent blogs. Before you begin: If you are working in a multi-user environment, ensure that you have "Modify" permissions for the Styles directory under the Publishing folder. Make a copy of the current styles. This recommendation is for backup purposes. If something goes wrong, you will have a way to recover. Consider creating your own category by creating a new folder under the Styles directory, and then copying the styles into your new folder. When you upgrade to future versions, the system will overwrite the standard styles with any new feature additions and updates that have been made. With your own category, all of your customizations will remain intact. To update the logos in all outputs: From the Tools Menu, choose Customize Logo. Select the category if necessary. Browse to select your logo. You can use any size logo, in any graphic format (*.bmp, *.gif, *.jpeg, *.jpg, *.png, or *.tif). The system will make a copy of your logo and add it to each of the publishing styles. Choose OK, and the update process begins. It may take a few minutes. Helpful hints: The logo you select is used "as is" - no resizing or cropping occurs during this process. The Customize Logo process automates replacing all the logo graphics for online deployment (small_logo.gif and large_logo.gif) and the headers in the documentation outputs. You can manually replace these graphics on an individual style basis if you prefer. The recommended logo size is 230 pixels wide x 44 pixels high. Prior to updating the logos, the system will display the size of the selected logo. If you use a logo that is much larger than the recommended size, the heading area will resize to fit the new logo, but that will impact the space available for your training material. If you are using a multi-user environment, the system will check out the publishing styles to you for the logo updates. After you review the styles, remember to check them in so the rest of your team can access the new changes. I'd be interested in hearing (or seeing) how you brand your UPK. Feel free to share in the comments! --Maria Cozzolino, Manager of Requirements & UI for UPK Product Development PS. For those of you who want to customize the player and documentation NOW, check out the detailed instructions in the Publishing Content chapter of the Content Development Guide.

  • Will client side performance improve if images/scripts/styles on different subdomains?

    - by Andrey
    Hi, I have a domain specifically for static content, so cookies don't travel along with requests to images/scripts/css. Now, I think I've read somewhere that most browsers only open one download thread for each domain/subdomain, so different static content can't be downloaded in parallel if on the same domain. Will it make difference for browsers if i place scripts in script.mycdn.com, styles in css.mycdn.com and images in images.mycdn.com? Will it allow to let browser download images at the same time as scripts and styles? mycdn.com is of course a made up name :) Thanks! Andrey

  • GWT: how to have different styles for splitters in different SplitLayoutPanels?

    - by user26270
    I know you can change the styles of the splitters with the defaults styles listed in the docs: .gwt-SplitLayoutPanel .gwt-SplitLayoutPanel-HDragger { horizontal dragger } .gwt-SplitLayoutPanel .gwt-SplitLayoutPanel-VDragger { vertical dragger } and we've done that in earlier development. However, now I'm developing new stuff and would like to use a different style for the splitters in a new SplitLayoutPanel. Unfortunately, we haven't or can't split the app into different modules, which might make this easier. I tried creating a new style and applying it to my new SplitLayoutPanel, but it didn't appear to have any effect on the splitters. I thought there might be a method to get a handle on the splitters in order to apply the new style to only them, but I didn't find any such method.

  • Does a VCL OrgChart component with decent features exists? Is there a viable alternative?

    - by user193655
    I am using DevExpress OrgChart component that is still maintained but not developed since 2003 (fortunately bugs are fixed, but nothing more). Honestly this component, even if it starts to look too old still suffices my requirements except for 2 things: 1) it doesn't support at all the staff feature, for understanding what I mean see this image (where the items in staff are Administration, Communication, IT, Special Projects). 2) it arranges the items without optimizing the space, for example if there are 3 items at top level, and only the second item has 2 childs, the top items items are drawn more distantly, because of the 2 childs, there is no an option for "shirinking" the diagram. Of course the component misses tons of the features one would expect from an OrgChart tool, but in my case Those 2, and expecially (1) are important, the rest is lack of eye-candy. I look for VCL components, but if (as I fear, since I never found it) such component doesn't exist) I can see the following alternatives: i) using Hydra with .net winforms components ii) using ActiveX components. Between the 2 I would prefer ActiveX because of the .NET deployment hell (what I like about Delphi is that you ship the exe to the customer witn Win2k and it works). Anyway I never used an activeX control and I don't know which are the deployment issues, but I fear I will lose the opportunity of replacing an exe and upgrading the software. iii) hire a delphi component develoeper that can customize the DevEx component by adding feature (1) and maybe (2). I am stuck.

  • Using VCL for the web (intraweb) as a trick for adding web interface to a legacy non-tiered (2 tiers

    - by user193655
    My team is maintaining a huge Client Server win32 Delphi application. It is a client/server application (Thick client) that uses DevArt (SDAC) components to connect to SQL Server. The business logic is often "trapped" in Component's event handlers, anyway with some degree of refactoring it is doable to move the business logic in common units (a big part of this work has already been done during refactoring... Maintaing legacy applications someone else wrote is very frustrating, but this is a very common job). Now there is the request of a web interface, I have several options of course, in this question i want to focus on the VCL for the web (intraweb) option. The idea is to use the common code (the same pas files) for both the client/server application and the web application. I heard of many people that moved legacy apps from delphi to intraweb, but here I am trying to keep the Thick client too. The idea is to use common code, may be with some compiler directives to write specific code: {$IFDEF CLIENTSERVER} {here goes the thick client specific code} {$ELSE} {here goes the Intraweb specific code} {$ENDIF} Then another problem is the "migration plan", let's say I have 300 features and on the first release I will have only 50 of them available in the web application. How to keep track of it? I was thinking of (ab)using Delphi interfaces to handle this. For example for the User Authentication I could move all the related code in a procedure and declare an interface like: type IUserAuthentication= interface['{0D57624C-CDDE-458B-A36C-436AE465B477}'] procedure UserAuthentication; end; In this way as I implement the IUserAuthentication interface in both the applications (Thick Client and Intraweb) I know that That feature has been "ported" to the web. Anyway I don't know if this approach makes sense. I made a prototype to simulate the whole process. It works for a "Hello world" application, but I wonder if it makes sense on a large application or this Interface idea is only counter-productive and can backfire. My question is: does this approach make sense? (the Interface idea is just an extra idea, it is not so important as the common code part described above) Is it a viable option? I understand it depends a lot of the kind of application, anyway to be generic my one is in the CRM/Accounting domain, and the number of concurrent users on a single installation is typically less than 20 with peaks of 50. EXTRA COMMENT (UPDATE): I ask this question because since I don't have a n-tier application I see Intraweb as the unique option for having a web application that has common code with the thick client. Developing webservices from the Delphi code makes no sense in my specific case, so the alternative I have is to write the web interface using ASP.NET (duplicating the business logic), but in this case I cannot take advantage of the common code in an easy way. Yes I could use dlls maybe, but my code is not suitable for that.
