Application_BeginRequest Not Being Fired In Stressed Environment?
Dec 14, 2010
We are obesrving strange problems when performing sress test of our applciation. We use Application_BeginRequest and Application_EndRequest to log the beginning and end of the web request, together, with the thread id.
However, from our logs, we see that Application_Begin_REquest is not being fired:
We use the following code to do the logging in global.asax.cs:
You can see that there are two "End request" in the last two lines, but there is no (Begin) Request for the last log line.Our Dbg.WriteLine uses System.Diagnostics trace listeners to ouput data to the file.
Environment: Windows Server 2008 R2, ASP.NET 3.5
This only happens when performin stress test. CPU utilization is around 60%, there are max 10 concurent requests executing.
UPDATE: I have found out that some other also did have similar problems (althoug in different configuration:

UPDATE#2: This night be related to fact, that Thread.GetHashCode() which is used to print out the thread identifier in our log fies could change. See ASP.NET - Thread.GetHashCode() changes
function LogInUser() { var LoginName = document.getElementById("<%=txt_LoginName.ClientId %>").value; var Password = document.getElementById("<%=txt_Password.ClientId%>").value;
I have two versions of a website. One runs on IIS server on a local PC, the other runs on the ASP.NET development environment included on Visual Studio (localhost). Apart from that, the file stucture of both is the same, although only the one running on IIS works properly, and this seems to be related to the fact that the IIS version calls Application_BeginRequest() where the other doesn't.
I've looked at the differences between IIS server and the ASP development environment in: [URL], and it says that IIS and the ASP development server deal with static content in that for IIS in that on IIS static content does not go through the ASP.NET runtime like it does on the dev environment (but I'm not sure exactly what this means).
I've done a number of tests involving images, etc, and have noticed that when the image is of the form:
<img src="Image/MyImage.jpg...>
the IIS server version calls Application_BeginRequest(), but the visual studio development environment version doesn't.
In my case, it is necessary to call Application_BeginRequest because this creates a new path and calls RewritePath().
The problem occurs when using links such as <a href="..." ...>, because if I use static content it won't call Application_BeginRequest() and the path won't be re-written. But If I change it to href=" %=ResolveUrl("~/...")%>" (for some reason, it will only call BeginRequest() if the path begins with a tilde ~), the path is re-written incorrectly.
I'm not really sure how to find out why the IIS version is calling Application_BeginRequest() from all the time (the callstack just says "external code"), or why it is calling it whereas the local dev server version isn't.
If anybody can explain this, or knows of any sites that go into this so I can master the basics, I'd be very grateful.
I've seen a few posts about Application_BeginRequest, but non seems to have my problem.
My Application_BeginRequest is being called for every image in my website.
The StaticFile Handler is enabled with * as the Path, but it's at the end of the list.
Is this the normal behaviour? Or should I add .gif, .jpg and so on on top of the list?
This is on my IIS7.5 Win7 Development Server. Didn't check it on the production server yet.
Update: Setting runAllManagedModulesForAllRequests=false would help. But then the ASP.NET URL Mapping does not work anymore. I tried disable it just for the image directly, but that had no effect?
I have a site with multiple domains pointing to it. I wanted to redirect all requests to main domain so I've created a method called RedirectToRealDomain("domain.com") to check and redirect all requests to my preferred domainAt the moment it lives on Session_Start but I am planing to move it to Application_BeginRequest event. As I understand Session_Start only raised when new session started but Application_BeginRequest raised on all requests. RedirectToRealDomain method doesn't do any DB lookups or anything expensive apart from comparing strings.
I've got some tracing statements with timestamps on an ASP.Net IIS application that gets a lot of traffic. I've got trace statements at the end of Application_BeginRequest and the beginning of Application_PreRequestHandlerExecute in my Global.asax. Occasionally there is a big delay between the end of BeginRequest and the start of PreRequestHandlerExecute, i.e. more than 5 seconds.
What is going on in the lifecycle of an HttpRequest between these two method calls that could be taking so long? This is IIS7 on Windows Server 2008.
I'm trying to get a reference to the user object in my Global.asax file's Application_BeginRequest. I'm using the property Context.User but I get a NullReferenceException. Is it possible to get a user object reference in Application_BeginRequest?
I am trying to create a 404 handling page but I am now stuck with the page only working for .aspx files, which isn't really what I need.I am running on IIS6.The site has a wildcard mapping,for extensionless URLs.All requests go through Application_BeginRequest in Global.asax but not all errors go through Application_Error.Is there a way where I can get the Application_Error to raise for non .aspx files?
I created a web service on localhost, and I tried to call it from a web app (also on the localhost) via HttpWebRequest, but Application_BeginRequest in Global.asax didn't fire. When I type in IE 'http://localhost:8010/Test/' (the web service) Application_BeginRequest fires. Where is the problem? How can I test a localhost web service from a page which is also on localhost?
I have a problem using Application_BeginRequest and I have absolutely no clue what is going on. When using this code, my website works fine:
[Code]....
Now, when I only alter it like this (note that I am actually doing nothing special):
[Code]....
This small change in code causes that forms don't postback anymore. I am truely clueless why this happens when trying to get some request.form variables.Stupid thing is, when debugging the website using visual studio, everything works fine.
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
Is there a way to retrieving parameter names and values passed to a web method from Request object? I've read somewhere that you need extra code to access the soap body. Any known workarounds to be able to see the soap body from Application_BeginRequest?
I want to protect one file in a subdirectory with Global.asax. (I know that this isn't the conventional way of going about this) but it works on my computer and not on the server.I have a global.asax file in my root dir and Application_BeginRequest checks if the user is requesting a particular file. If they are logged in, it allows access. If they are not logged in they are redirected to the default page.My problem is this: My code works on my personal computer but does not work on the server. Do I have to configure a setting in the web.config or adjust something on the server? Code:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) Dim fullOrigionalpath As String = Request.Url.ToString.ToLower 'PROTECTED FILE If fullOrigionalpath.Contains("/uploads/groups.xls") Then If HttpContext.Current.User.Identity.IsAuthenticated = False Then Response.Redirect("~/login.aspx") End If End Sub
I fill a third-pard component variable in Global.Application_BeginRequest(). Everything is fine until I set IIS7 into the Integrated mode. In that case the method Application_BeginRequest() is not called (Application_Start is ok).May be some module is registered wrong?(I have found a same problem here on forum, but without a solution:[URL]
I am doing some redirecting of old url in global.asax's application_beginrequest. Redirecting works fine when getting the url's using an http get but not when using an http head request.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.
At our company we are going to develop more for the Windows platform than we have done up until now. As this scale of Windows development is new to us it would be nice with some feedback from experienced developers. Requirements we have: 5 developers from the beginning. 15 developers a year from now. All developers should be able to develop at the same time. Be able to develop solution for ASP.NET and EpiServer 5. Our idea:
A shared server which developers use for development through Terminal Services. SQL Server Express. Start with some free express edition of Visual Studio, upgrade to a commercial version if we need the additional features. Use IIS and not the web server built into Visual Studio. Questions:
Are we on the right track?
In terms of license costs the above should be cheapest, right?
What do you think about multiple developers doing development using a shared TS-server?
Do you know of any company which has a similar development environment?
Are we going to miss some features of the full Visual Studio version immediately? Is using Express version a bad choice? Is IIS the best choice? If use IIS the developers may use the same port for deployment. If we use the built in web server each one has to set their own port as we're sharing a machine.
Comment answer: We are thinking about a shared server as it will most likely decrease the license costs. So it's purely a cost issue. We are using CVS for version control. Our situation is that we develop on Mac and Linux, that's why buying 1 server license + Visual Studio licenses seems to be a cost effective way of starting this type of development.
My dev team and I would like to setup a development environment for our ASP.NET projects. BY development environment i do not mean Visual Studio. I mean, that we have a Database Server, a Application Server and a Web Server in a 'Development Environment'. We want to use this as our integration environment. Where the developers all work on there parts of ASP.NET Applications and then we can push our new changes up to test them as a whole. My Question is , what is the best way to deploy our code together without stepping on our toes?
This is a general question about dealing with URL Rewriting in a development environment. I'm developing a CMS to learn ASP.NET/C#, and I will of course need to implement URL Rewriting. This technique is known to me since I've been using with PHP for several years. However in PHP, you can have a local HTTP server, modify the PHP content directly, refresh the page and see the results. Of course in ASP.NET it's not exactly the same, since you need to compile and then publish the code. The problem I have is that I need to check the URL Rewriting-friendly links my code will generate in my development environment - basically, make the ASP.NET Development Server compatible with URL Rewrite. Or maybe not. My question really is: what is the best solution to do that? Use IIS/Apache2 (w/ Mono) for the development server?
I'm from PHP background. I used to use Apache, MySQL and PHP for web development. I'm just starting asp.net mvc. I've Visual Studio 2008 Pro SP1 & .NET 3.5 SP1 already installed on my computer. So, I installed ASP.NET MVC 1.0 Created a "ASP.NET MVC Web Application" project when I hit F5 it gives error Unable to connect to the ASP.NET Development Server No wonder. In this process I didn't setup the webserver. Can I use apache here? I guess IIS is the default. Where is it? How do I configure it? What is the WebRoot directory for IIS server? Where can I find it? On searching for "Unable to connect to the ASP.NET Development Server" I found this solution:
Step 1: Select the "Tools->External Tools" menu option in VS or Visual Web
Developer. This will allow you to configure and add new menu items to your Tools menu.
Step 2: Click the "Add" button to add a new external tool menu item. Name it "WebServer on Port 8010" (or anything else you want).
Step 3: For the "Command" textbox setting enter this value: C:WINDOWSMicrosoft.NETFrameworkv2.0.50727WebDev.WebServer.EXE (note: this points to the web-server that VS usually automatically runs).
Step 4: For the "Arguments" textbox setting enter this value: /port:8010 /path:$(ProjectDir) (or any port you like)
Step 5: Select the "Use Output Window" checkbox (this will prevent the command-shell window from popping up. Once you hit apply and ok you will now have a new menu item in your "Tools" menu called "WebServer on Port8010". You can now select any web project in your solution and then choose this menu option to launch a web-server that has a root site on port 8010 (or whatever other port you want) for the project. You can then connect to this site in a browser by simply saying [URL] All root based references will work fine.
Step 6: The last step is to configure your web project to automatically reference this web-server when you run or debug a site instead of launching the built-in web-server itself. To-do this, select your web-project in the solution explorer, right click and select "property pages". Select the "start options" setting on the left, and under server change the radio button value from the default (which is use built-in webserver) to instead be "Use custom server". Then set theBase URL value to be: [URL] But there is no C:WINDOWSMicrosoft.NETFrameworkv2.0.50727WebDev.WebServer.EXE such file on my system. Did I forget to install something?
EDIT:
I'm using Windows XP SP2 and logged in as a user with Administrative previlages. from this [URL]
Disable IPv6
Done
Make sure there isnt an edit in the hosts file for localhost There is no single entry in my hosts file (%SystemRoot%system32driversetchosts) with 'localhost' in it. Check firewall/virus settings to allow connections to/from devenv.exe I tried by disabling the firewall/antivirus If you can preview in the browser make sure the URL in the browser uses the same port number as the port number shown in the ASP.NET dev server taskbar icon. No, Actually there is no such dev server taskbar icon. Try setting a fixed, predefined port in project properties Tried it. But no positive result. S
Solution:
After trying everything. I came to conclusion that WebDev.WebServer.exe may be corrupt. So, I've replaced C:Program FilesCommon Filesmicrosoft sharedDevServer9.0WebDev.WebServer.EXE with a fresh copy : [URL]
I have a project in VS 2010 and works great in my dev environment, including a single post that has the def:
[Code]....
But when I publish to another box, I get an error "Could not instantiate file name generator.". This only occurs on the post, all the other ActionResults work fine.
I am starting a new project. I can either use the Entity Framework 4.0 or Linq to SQL as my data access layer. I don't have any experience using either product. I have read a lot about how Linq to SQL suffers in a disconnected environment like ASP.NET. I was wondering if the Entity Framework suffers from the same problems or if it is works well in a web environment. I was also wondering if someone could recommend a good tutorial or book on the Entity Framework 4.0.
