  • The Mysterious ARR Server Farm to URL Rewrite link

    - by OWScott
    Application Request Routing (ARR) is a reverse proxy plug-in for IIS7+ that does many things, including functioning as a load balancer.  For this post, I’m assuming that you already have an understanding of ARR.  Today I wanted to find out how the mysterious link between ARR and URL Rewrite is maintained.  Let me explain… ARR is unique in that it doesn’t work by itself.  It sits on top of IIS7 and uses URL Rewrite.  As a result, ARR depends on URL Rewrite to ‘catch’ the traffic and redirect it to an ARR Server Farm. As the last step of creating a new Server Farm, ARR will prompt you with the following: If you accept the prompt, it will create a URL Rewrite rule for you.  If you say ‘No’, then you’re on your own to create a URL Rewrite rule. When you say ‘Yes’, the Server Farm’s checkbox for “Use URL Rewrite to inspect incoming requests” will be checked.  See the following screenshot. However, I’m not a fan of this auto-rule.  The problem is that if I make any changes to the URL Rewrite rule, which I always do, and then make the wrong change in ARR, it will blow away my settings.  So, I prefer to create my own rule and manage it myself. Since I had some old rules that were managed by ARR, I wanted to update them so that they were no longer managed that way.  I took a look at a config in applicationHost.config to try to find out what property would bind the two together.  I assumed that there would be a property on the ServerFarm called something like urlRewriteRuleName that would serve as the link between ARR and URL Rewrite.  I found no such property.  After a bit of testing, I found that the name of the URL Rewrite rule is the only link between ARR and URL Rewrite.  I wouldn’t have guessed.  The URL Rewrite rule needs to be exactly ARR_{ServerFarm Name}_loadBalance, although it’s not case sensitive. Consider the following auto-created URL Rewrite rule: And, the link between ARR and URL Rewrite exists: Now, as soon as I rename that to anything else, for example, site.com ARR Binding, the link between ARR and URL Rewrite is broken. To be certain of the relationship, I renamed it back again and sure enough, the relationship was reestablished. Why is this important?  It’s only important if you want to decouple the relationship between ARR the URL Rewrite rule, but if you want to do so, the best way to do that is to rename the URL Rewrite rule.  If you uncheck the “Use URL Rewrite to inspect incoming requests” checkbox, it will delete your rule for you without prompting.  Conclusion The mysterious link between ARR and URL Rewrite only exists through the ARR Rule name.  If you want to break the link, simply rename the URL Rewrite rule.  It’s completely safe to do so, and, in my opinion, this is a rule that you should manage yourself anyway.

  • Allen for Umbraco - Upload photos from your iPhone - iPad and iPod Touch

    - by Vizioz Limited
    At last year's UK Umbraco Festival we gave a demo of our alpha version of Allen for Umbraco, at that stage the application only worked on an iPhone and was a very quick prototype to see what people thought.When we returned to our office the next day, we decided if we were going to release Allen for Umbraco into the wild we really should start again from scratch, the main two reasons for this were;First to ensure it was a truly Universal application ( i.e. it can be installed on an iPhone, iPad or iPod ) which looks and behaves differently depending on the device. The second reason was we really wanted the application to be the foundations of more than just image uploading for Umbraco, for this to be the case we ensured the new version was built following proven design patterns and with lots of unit tests so that we can easily extended it.We have lots of plans for future versions of Allen for Umbraco including adding iCloud support to keep all your settings in sync across your multiple Apple devices. We are also working on support for Umbraco 5 which should be release soon.When you download the App and setup your site, make sure you have a look at the Image Resizing settings, by default we have set these to resize your images to 512 pixels wide, however you can choose from a variety of different resizing methods (by Height, Width, Fit within a frame or the full size image).Also, by default when you select a photo you will see that the image is named with it's date and time stamp of when the photograph was taken (or the current date and time if the original date is not stored in your image). If you click on this name you can edit the name of your photo before it is uploaded.Finally, we are really keep to get your feedback, so within the App help section you will find a way to submit Suggestions and if needed, you can send up Support emails from within the App :)We hope you enjoy the first version of Allen for Umbraco and we look forward to bringing you lots of exciting additional functionality in the future!

  • mixing different technologies using ARR reverse proxy

    - by Jaepetto
    I'm currently trying to put together a proof of concept on mixing various technologies onto one web site in order to ease migrations and add flexibility. The idea is to create one 'mashup' site behind an IIS 7.5 ARR reverse proxy. For the time being the ARR reverse proxy forwards all request to our main site. The request are as follow: client -> ARR: Get / ARR -> Server 1: Get / Server 1 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ...so far so good. Let's say, I want to add a new site (root of another server) as a subsite of my main website. a simple inbound rule does the trick: <rule name="sub1" stopProcessing="true"> <match url="^mySubsite(.*)" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false" /> <action type="Rewrite" url="http://server2/{R:1}" /> </rule> The requests now are: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ... still ok. The issue comes when the site on server2 sends a redirection (e.g. to a login page). In the case of SharePoint, it will redirect the user to: /_layouts/Authenticate.aspx?Source=%2F ...which does not exists: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 301: /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 301: /_layouts/Authenticate.aspx?Source=%2F client -> ARR: Get /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 404: Not Found Does anyone know a way write the outbound rule to rewrite the response from server 2 "301: /_layouts/Authenticate.aspx?Source=%2F" to "301: /mySubsite/_layouts/Authenticate.aspx?Source=%2FmySubsite%2F"?

  • Allen for Umbraco with location EXIF meta data

    - by Vizioz Limited
    The latest version of Allen for Umbraco has now hit the Apple App store, we have managed to add some nice improvements to this version that include:Storing location and direction information when photos are taken within the AppEmbedding EXIF data into the images when they are uploadBackground UploadingPull to refresh the media tree Location and DirectionBy default when the camera is used within an application the location and direction that the camera is pointing is not stored within the image meta data. We have now added full support so that this data is now added. We have added a setting which allows you to prevent this data from being uploaded to your website if you do not want the location data to be sent you can turn it off within Allen, Note: Please don't forget that location services do need to be turned on to allow the app to access the images in the phone's asset library.We have had quite a few ideas from users already for using this location data, including logging free parking in Denmark to geo-tagging holiday photos and linking the photos to Google street view. Embedding EXIF dataWe now embed all the meta data available on the iPhone into the image when it is uploaded to your server, this allows you to pull the data out and use it within your site. Have a look at Cultiv's Photo Meta Data package for great example code that allows you to automatically pull this data out and populate properties on your Umbraco media item.We slightly modified the source code of this package to allow the package to always extract the image data, as the default package requires a property to allow the data to be extracted, it's an easy change, if you get stuck add a comment to this post. Background UploadingIf you try to upload multiple images and need to start doing something else on your phone, you can now click the home button and the application will continue to upload your images in the background. As soon as it has finished you will receive a standard Apple notification. Pull to RefreshOur final enhancement has been to add "Pull to refresh" to the media trees, just pull the tree downwards with your finger and it will refresh, this is useful if you are adding items to your media tree while testing your site with Allen for Umbraco. Future enhancements.. your ideas?If you have any ideas for future enhancement feel free to add a comment below!

  • SQLAuthority News – Meeting with Allen Bailochan Tuladhar – An Unlimited Experience

    - by pinaldave
    Allen  Tuladhar I recently came back from my 9-day trip in Nepal and I must say that this is one of the best trips I had in my lifetime. Allen Bailochan Tuladhar is a wonderful person and an extreme enthusiast for Microsoft Technology. Allen is the Chief Executive Officer of Unlimited Technologies Pvt Ltd., Country Manager of Microsoft MDP Nepal, the Member Secretary of Nepali Language in Information Technology, and member of the Steering Committee of the Government of Nepal. He is the person who keeps the Nepal’s Tech Community constantly motivating and taking it to the next level. I have met Allen for many times before, but this was the first time I was with him in Kathmandu, Nepal. I was very impressed with the amount of the work he does in the community. During my 9 days of stay, every single day was a new lesson for me. I was amazed and overwhelmed with the many things he does every single day. Not only he does he work closely with Government of Nepal ministry, but he is also the most known person in the Student Community. His expertise in the technical subject matter is not limited to one technology; rather, I have seen him actively engaging himself in  discussions of various tech topics. Allen presending at TechMela Kathmandu, Nepal Allen is currently active in working out to localize Windows and Office and incorporate it using the Nepali language. I was able to witness and experience how the localization works, as well as the procedure on how to do such. If you know the whole localization process, you must have realized how big and daunting of a process it is. I was glad that I became a part of it. Prominent Personality of Nepal on Panel Discussion Another great opportunity I had when I was at Allen’s office is that I have learned how the radio technology talk show works. Nepali Radio station has the weekly program in their local language, in which MS technology is discussed and industry leaders are invited to talk about their experience with the technology. I found the program so interesting because it has so much variety in terms of technology subjects. Well, my understanding of Nepali language is limited but I did understand quite a bit. Ravi, Nutan, Pinal, Gandip I got the chance to meet lots of Database Professionals as well. People in Nepal are very polite even though they are very strong in their technology fundamentals. I had in-depth discussion regarding High Availability scenarios, as well Query Tuning. Database professionals from the leading financial sectors of Nepal wanted me to visit their Data Center and help them out with a few advances. In no time, Allen organized a visit for me. He sent me a Nepali-speaking expert from his own organization to accompany me in overcoming any difficulties while I was on my way helping this financial district. Pinal (SQLAuthority) and Deependra (Unlimited) When I was going to Nepal, I was really not sure if I would be able to stay busy for 9 days straight in Community-related activity. However, on the 9th day I realize that I can still stay here for more than 9 days because in every single day, I feel enthusiastic enough to do something new. Allen Bailochan Tuladhar Even though I was working  very hard every day, I hardly had the chance to work with and talk to him one-on-one for the first few days. One of the evenings, Allen invited me to his home and we discussed about his future ideas. I was really surprised to see how much a man can do for his technical community and for his country. When I asked Allen’s wife and daughter if they ever think it’s getting too much with regards to Allen putting tough efforts to the community, their answer was something I did not expect. I found out that Allen’s wife manages all the back office and logistics of the community events and his daughter manages the websites. I felt that they do not have any complain,  and instead, their whole family is in this activity as deeply as it can get, which I thought is a very good thing. Pinal and Allen I want to end this post with an interesting story that happened during our lunch hour at one of the Nepali restaurants. While we were having our lunch and having some chitchat, Allen suddenly stood up and called several people walking along the pavement. He introduced them all to me as Microsoft Student Partners. He asked all of them to order their favorite dish and called the waiter to inform that he will pick up their tab. Figuring out the question written on my face, he just said one sentence: “They are all future technology professionals who are going to make all of us proud.” I guess I have a lot of things to learn. Hats off to Allen!

  • iis 7.5 - WFF and ARR farm management

    - by smackaysmith
    We have two test web farms (IIS 7.5). The Florida web farm has two ARR servers and two content servers. The ARR servers have WFF and NLB installed. The ARR setup uses a shared config located on a file share. The content servers do not have WFF installed. There is one web farm, and it's managed on an ARR server. The Illinois web farm also has two ARR servers and two content servers. ARR servers have WFF and NLB installed, and they use a shared config located on a share. One of the content servers has WFF installed, which makes it the controller; it's also the primary content server. Apparently, Illinois isn't properly configured. From what we've pieced together from various IIS.net articles and this post (http://ruslany.net/2010/07/web-farm-framework-2-0-overview/), the controller should be one of the ARR servers (like our Florida setup). The thing is Florida's controller doesn't have a Primary server nor can you set one of the content servers as Primary. It doesn't have the management piece showing the Trace messages when you click the Servers node (from iis console, Server Farms/FLFarm/Servers http://ruslany.net/wp-content/uploads/2010/07/WebFarm8.png). That management piece does exist in the Illinois farm, but that's a bad configuration. What are we missing that our Florida configuration doesn't have the Primary and Secondary content servers, and the management piece? I have looked for IIS role differences, but there are none.

  • Setting up a Reverse Proxy using IIS, URL Rewrite and ARR

    - by The Official Microsoft IIS Site
    Today there was a question in the IIS.net Forums asking how to expose two different Internet sites from another site making them look like if they were subdirectories in the main site. So for example the goal was to have a site: www.site.com expose a www.site.com/company1 and a www.site.com/company2 and have the content from “www.company1.com” served for the first one and “www.company2.com” served in the second one. Furthermore we would like to have the responses cached in the server for performance...(read more)

  • Bad request - Invalid Hostname Error when using ARR IP address

    - by syloc
    I'm trying to setup a simple ARR system. I have 1 ARR machine load balancing between 2 APP servers. I can reach the app sites if i use the server name of the ARR machine. (http://arrserver/app) But i can't do it with its IP address. (http://10.7.10.25/app). It gives the "Bad Request - Invalid Hostname". In the ARR machine i configured the default site's bindings to "All Unassigned","80" (default values). Do i need to change the binding rule or need additional url rewrite rules? And also, in the ARR server http://127.0.0.1/app doesn't work. But http://localhost/app works fine. Thx in advance

  • Application Request Routing (ARR) - Single Server Reverse Proxy(ish) Setup

    - by Justin
    I have 1 webserver that has two .NET apps running on it. These are set up on the server as app1.mydomain.com and app2.mydomain.com. I would like to be able to take any request going to app1.mydomain.com/subfolder and rewrite it to app2.mydomain.com/subfolder using ARR. I am having difficulty getting this to work on a single server, and all the ARR examples on the net seem to imply that I require another server dedicated to ARR sitting in front of the two web servers. Is what I am attempting to do possible on one web server, and if so how?! Thanks all.

  • jQuery $.each(arr, foo) versus $(arr).each(foo)

    - by Brian M. Hunt
    In jQuery, what's the difference between the following two constructions of jQuery.each: // Given var arr = [1,2,3,4], results = [], foo = function (index, element) { /* something done to/with each element */ results.push(element * element); // arbitrary thing. } // construction #1 $.each(arr, foo); // results = [1,4,9,16] // construction #2 $(arr).each(foo); // results = [1,4,9,16] Is there any difference, or is it purely syntax?

  • Make server unavailable gracefully using Powershell in ARR

    - by Carl Bergquist
    We are using ARR as reverse proxy and I would like to make a server unavailable for various reasons. How can this be done using Powershell? Edit 1: I found this http://blogs.iis.net/anilr/archive/2009/11/09/using-arr-config-extensibility-to-gracefully-stop-server.aspx tutorial for using JScript. But I'm not able to translate it to powershell. Edit 2: Using the Set-WebConfigurationProperty in WebAdministration module I'm able to changes settings for a server. I found SetState in %windir%\system32\inetsrv\config\schema\arr_schema.xml but I don't know how to invoke that method.

  • ARR servers in the Load Balancing pool automatically go from unavailable to available

    - by Chris
    I have 3 IIS web servers in an ARR web farm. When we do rolling releases, we take one server offline as a backup server and move it into an "Unavailable State" I have noticed that with ARR, servers will not stay in this state...they come back online automatically hours or days later. Does anyone know how to remedy this situation? This is very bad as the server that is down is typically not running the correct version of our code. I need to keep a server unavailable until i tell it otherwise.

  • ARR troubleshooting 502.3 / WinHttp tracing on Server 2012

    - by nachojammers
    I have the following scenario: 3 windows server 2012 virtual servers, all with IIS 8: 1 server with Application Request Routing 3 2 servers with the web applications that the ARR server routes to I am getting intermittent 502 3 12002 errors. Following this guide http://www.iis.net/learn/extensions/troubleshooting-application-request-routing/troubleshooting-502-errors-in-arr I have identified that I need to trace using netsh the WinHttp/WebIO providers to get to the real error code that is mapped to the 12002 error code. I run the trace as the article suggests: netsh trace start scenario=internetclient capture=yes persistent=no level=verbose tracefile=c:\temp\net.etl When analysing the output of the netsh traces, I don't get the level of information that the article suggests I should. Specifically I only get the following types of entry in the trace viewed using netmon: WINHTTP_MicrosoftWindowsWinHttp:Stopping WorkItem Thread Action... WINHTTP_MicrosoftWindowsWinHttp:Starting WorkItem Thread Action... WINHTTP_MicrosoftWindowsWinHttp:Queue Overlapped IO Thread Action... I certainly don't get anything detailed enough that would help me understand why am getting any timeouts. Is there any reason why Server 2012 wouldn't trace the WinHttp API to the level I need? Thanks

  • How to find the insertion point in an array using binary search?

    - by ????
    The basic idea of binary search in an array is simple, but it might return an "approximate" index if the search fails to find the exact item. (we might sometimes get back an index for which the value is larger or smaller than the searched value). For looking for the exact insertion point, it seems that after we got the approximate location, we might need to "scan" to left or right for the exact insertion location, so that, say, in Ruby, we can do arr.insert(exact_index, value) I have the following solution, but the handling for the part when begin_index >= end_index is a bit messy. I wonder if a more elegant solution can be used? (this solution doesn't care to scan for multiple matches if an exact match is found, so the index returned for an exact match may point to any index that correspond to the value... but I think if they are all integers, we can always search for a - 1 after we know an exact match is found, to find the left boundary, or search for a + 1 for the right boundary.) My solution: DEBUGGING = true def binary_search_helper(arr, a, begin_index, end_index) middle_index = (begin_index + end_index) / 2 puts "a = #{a}, arr[middle_index] = #{arr[middle_index]}, " + "begin_index = #{begin_index}, end_index = #{end_index}, " + "middle_index = #{middle_index}" if DEBUGGING if arr[middle_index] == a return middle_index elsif begin_index >= end_index index = [begin_index, end_index].min return index if a < arr[index] && index >= 0 #careful because -1 means end of array index = [begin_index, end_index].max return index if a < arr[index] && index >= 0 return index + 1 elsif a > arr[middle_index] return binary_search_helper(arr, a, middle_index + 1, end_index) else return binary_search_helper(arr, a, begin_index, middle_index - 1) end end # for [1,3,5,7,9], searching for 6 will return index for 7 for insertion # if exact match is found, then return that index def binary_search(arr, a) puts "\nSearching for #{a} in #{arr}" if DEBUGGING return 0 if arr.empty? result = binary_search_helper(arr, a, 0, arr.length - 1) puts "the result is #{result}, the index for value #{arr[result].inspect}" if DEBUGGING return result end arr = [1,3,5,7,9] b = 6 arr.insert(binary_search(arr, b), b) p arr arr = [1,3,5,7,9,11] b = 6 arr.insert(binary_search(arr, b), b) p arr arr = [1,3,5,7,9] b = 60 arr.insert(binary_search(arr, b), b) p arr arr = [1,3,5,7,9,11] b = 60 arr.insert(binary_search(arr, b), b) p arr arr = [1,3,5,7,9] b = -60 arr.insert(binary_search(arr, b), b) p arr arr = [1,3,5,7,9,11] b = -60 arr.insert(binary_search(arr, b), b) p arr arr = [1] b = -60 arr.insert(binary_search(arr, b), b) p arr arr = [1] b = 60 arr.insert(binary_search(arr, b), b) p arr arr = [] b = 60 arr.insert(binary_search(arr, b), b) p arr and result: Searching for 6 in [1, 3, 5, 7, 9] a = 6, arr[middle_index] = 5, begin_index = 0, end_index = 4, middle_index = 2 a = 6, arr[middle_index] = 7, begin_index = 3, end_index = 4, middle_index = 3 a = 6, arr[middle_index] = 5, begin_index = 3, end_index = 2, middle_index = 2 the result is 3, the index for value 7 [1, 3, 5, 6, 7, 9] Searching for 6 in [1, 3, 5, 7, 9, 11] a = 6, arr[middle_index] = 5, begin_index = 0, end_index = 5, middle_index = 2 a = 6, arr[middle_index] = 9, begin_index = 3, end_index = 5, middle_index = 4 a = 6, arr[middle_index] = 7, begin_index = 3, end_index = 3, middle_index = 3 the result is 3, the index for value 7 [1, 3, 5, 6, 7, 9, 11] Searching for 60 in [1, 3, 5, 7, 9] a = 60, arr[middle_index] = 5, begin_index = 0, end_index = 4, middle_index = 2 a = 60, arr[middle_index] = 7, begin_index = 3, end_index = 4, middle_index = 3 a = 60, arr[middle_index] = 9, begin_index = 4, end_index = 4, middle_index = 4 the result is 5, the index for value nil [1, 3, 5, 7, 9, 60] Searching for 60 in [1, 3, 5, 7, 9, 11] a = 60, arr[middle_index] = 5, begin_index = 0, end_index = 5, middle_index = 2 a = 60, arr[middle_index] = 9, begin_index = 3, end_index = 5, middle_index = 4 a = 60, arr[middle_index] = 11, begin_index = 5, end_index = 5, middle_index = 5 the result is 6, the index for value nil [1, 3, 5, 7, 9, 11, 60] Searching for -60 in [1, 3, 5, 7, 9] a = -60, arr[middle_index] = 5, begin_index = 0, end_index = 4, middle_index = 2 a = -60, arr[middle_index] = 1, begin_index = 0, end_index = 1, middle_index = 0 a = -60, arr[middle_index] = 9, begin_index = 0, end_index = -1, middle_index = -1 the result is 0, the index for value 1 [-60, 1, 3, 5, 7, 9] Searching for -60 in [1, 3, 5, 7, 9, 11] a = -60, arr[middle_index] = 5, begin_index = 0, end_index = 5, middle_index = 2 a = -60, arr[middle_index] = 1, begin_index = 0, end_index = 1, middle_index = 0 a = -60, arr[middle_index] = 11, begin_index = 0, end_index = -1, middle_index = -1 the result is 0, the index for value 1 [-60, 1, 3, 5, 7, 9, 11] Searching for -60 in [1] a = -60, arr[middle_index] = 1, begin_index = 0, end_index = 0, middle_index = 0 the result is 0, the index for value 1 [-60, 1] Searching for 60 in [1] a = 60, arr[middle_index] = 1, begin_index = 0, end_index = 0, middle_index = 0 the result is 1, the index for value nil [1, 60] Searching for 60 in [] [60]

  • Morgan Stanley chooses Solaris 11 to run cloud file services

    - by Frederic Pariente
    At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as it calls it in his blog. Mike used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Mike is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

  • Linux to Solaris @ Morgan Stanley

    - by mgerdts
    I came across this blog entry and the accompanying presentation by Robert Milkoski about his experience switching from Linux to Oracle Solaris 11 for a distributed OpenAFS file serving environment at Morgan Stanley. If you are an IT manager, the presentation will show you: Running Solaris with a support contract can cost less than running Linux (even without a support contract) because of technical advantages of Solaris. IT departments can benefit from hiring computer scientists into Systems Programmer or similar roles.  Their computer science background should be nurtured so that they can continue to deliver value (savings and opportunity) to the business as technology advances. If you are a sysadmin, developer, or somewhere in between, the presentation will show you: A presentation that explains your technical analysis can be very influential. Learning and using the non-default options of an OS can make all the difference as to whether one OS is better suited than another.  For example, see the graphs on slides 3 - 5.  The ZFS default is to not use compression. When trying to convince those that hold the purse strings that your technical direction should be taken, the financial impact can be the part that closes the deal.  See slides 6, 9, and 10.  Sometimes reducing rack space requirements can be the biggest impact because it may stave off or completely eliminate the need for facilities growth. DTrace can be used to shine light on performance problems that may be suspected but not diagnosed.  It is quite likely that these problems have existed in OpenAFS for a decade or more.  DTrace made diagnosis possible. DTrace can be used to create performance analysis tools without modifying the source of software that is under analysis.  See slides 29 - 32. Microstate accounting, visible in the prstat output on slide 37 can be used to quickly draw focus to problem areas that affect CPU saturation.  Note that prstat without -m gives a time-decayed moving average that is not nearly as useful. Instruction level probes (slides 33 - 34) are a super-easy way to identify which part of a function is hot.

  • Microsoft Application Request Routing with Windows Authentication

    - by theplatz
    I'm running into a problem trying to get Windows Authentication working in an environment that uses Microsoft Application Request Routing and was hoping someone might be able to help. The problem I'm running into is that only some requests are authenticated, while others fail with 401 errors. I have followed the Special Case of Running IIS 7.0 in a Web Farm instructions found at http://blogs.msdn.com/b/webtopics/archive/2009/01/19/service-principal-name-spn-checklist-for-kerberos-authentication-with-iis-7-0.aspx to no avail. My current server setup looks like the following: ARR Two servers set up with IIS shared configuration using IIS 7.5 on Windows 2008 R2 Anonymous authentication turned on for the Default Web Site Web Farm Two servers running IIS 7.5 on Windows 2008 R2 Three web sites set up using port binding to differentiate between virtual hosts. Ports being used are 8000, 8001, and 8002 Application pools for Windows Authentication all use a common domain account SPN added to domain account for http/<virthalhost-name>:<port-number> and http/<virtualhost-name>.<fully-qualified-domain>:<port-number> The IIS logs show the following when authentication is working/failing. If I understand correctly, all requests should show DOMAIN\User_Name: 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/stylesheets/techweb.landing.css - 8002 DOMAIN\User_Name ARR-HOST-1-IP-ADDRESS 200 0 0 62 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-right.gif - 8002 - ARR-HOST-1-IP-ADDRESS 401 2 5 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-left.gif - 8002 DOMAIN\User_Name ARR-HOST-IP-ADDRESS 200 0 0 31 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 2 5 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 2148074248 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/application-icon.png - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 2148074248 0 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/user-background-right.gif - 8002 - ARR-HOST-1-IP-ADDRESS 401 1 3221225581 15 2012-11-19 15:03:17 CLUSTER-IP-ADDRESS GET /home/images/building.gif - 8002 DOMAIN\User_Name ARR-HOST-2-IP-ADDRESS 200 0 0 218 Does anyone know what might cause this problem and how I can resolve it?

  • Setting up an Active-Active IIS Cluster with ARR - is it possible?

    - by Ahmed Zubair
    I would like to know if we can setup an Active-Active IIS Cluster using Windows Cluster services that shares a common storage to store web content and WITHOUT the use of Windows NLB. I'm aware that this may not be a best practice or not a recommended setup, however, the setup is to be configured as below: Two web servers running IIS 7.5 (needs a common storage for web content) for HA and another set of two servers for sql cluster in active-passive mode for HA. Also is it possible to enable ARR on 2 node active-active IIS cluster for load balancing http requests? Appreciate if someone replies with both pros & cons of the setup.
