Web Forms :: When Is Application_BeginRequest Called?
Sep 2, 2010
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 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.
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 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?
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:
http://forums.iis.net/t/1154954.aspx) Matej
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
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?
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 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.
Please have a look at my VB/ASP code and tell me if you can see what's wrong (I have bolded the important segments):

Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying"feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.
Sometimes it works, most of the time it generate a crash with the following error
RegisterForEventValidation can only be called during Render(); Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: RegisterForEventValidation can only be called during Render();
Initially in my website page_load for the landing page say test.aspx was called twice everytime when it was getting loaded. Since my application is an upgraded one (from VS 2003 to VS 2005/2008), I commented the "this.load" event in InitializeComponent and it is working fine, when user first logs in, into my web application. But then, whenever user navigates to this page from any other page in my application, page_load gets called twice.
I have a page, which load a tab with usercontrol this usercontrol inturn loads an another usercontrol that has treeview. Issue: On (!Postback) of treeview control page_load, this load is gettting called twice. it is not callign the page_load of page but just the control page_load twice.
Tried: changed autoevenwireup from false to true, true to false (no change) Add/Remove of EnableViewState="true" ViewStateMode="Inherit" doesn't make any difference.
but if i add another usercontrolB and load that instead of this controlA, the ControlA still gets called on page_load once and ControlB also once.
I have a dropdownlist on a web form that isn't calling a routine when I click on a new item in the dropdown.Here's my code from the .aspx file
[Code].... [Code]....
My list is populated with a blank item as the 1st entry and then all the alerts that I have in my database. I originally had OnSelectedIndexChanged but that didn't work either.
I can't understand why the method LoadViewState() is not called after the postback in my code below.After label1 cahnges its text the "__VIEWSTATE" hidden field is modified, but LoadViewState() is not called.
In my web form, i am having button named "btnSave" and there are some textbox controls (to name few, Emp Number, Full Name, etc). I've added RegexValidator to the textbox controls as below:
<asp:RegularExpressionValidator ID="employeeNumberValidator" ValidationExpression="^[0-9]+$" ControlToValidate="txtEmpNumber" ErrorMessage="Only integers are allowed" runat="server"> </asp:RegularExpressionValidator>
This RegexValidator will check for emp number textbox contains only integers and if not, it will display message "Only integers are allowed". Now, in my btnSave_Click(...) event, i am first validating whether the textbox contains data and if not, then i am highlighting the textbox in red. When txtEmpNumber contains non-integers data and if i click the Save button, the code in inside btnSave_Click(...) event is not getting called. But when i provide employee number in expected format and then click Save button, then the code inside button click event is getting called without any issues.
I am not sure why my btnSave_Click(...) is not functioning when Employee Number has data in incorrect format.
