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?
View 2 RepliesI 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.
However, if I change the above code to use:
<img src="<%=ResolveUrl("~/Image/MyImage.jpg")%>" ...>
it will call Application_BeginRequest().
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?
<location path="Resources">
<system.webServer>
<modules runAllManagedModulesForAllRequests="false">
</modules>
</system.webServer>
<location>
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.
View 2 RepliesI'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 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?
This is the code inside the Application_Error
HttpException serverError = (HttpException)Server.GetLastError();
if (serverError != null) {

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:
protected void Application_BeginRequest(object sender, EventArgs e)
{
string url = ""; [code]....
This is our log file. Urls are omitted The 00013 column is thread id.
14.12.10 21:41:25.042 00013 00000 Request: 172.23.26.41
14.12.10 21:41:25.068 00013 00000 End request: 172.23.26.41
14.12.10 21:41:25.212 00013 00000 Request: 172.23.26.41

14.12.10 21:41:30.974 00013 00000 End request: 172.23.26.88
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)

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
How to handle Application_BeginRequest using a custom filter in asp.net mvc?
I want to restore session only for one route (~/my-url).
It would be cool, if I could create a custom filter and handle that.

var context = HttpContext.Current; [code]......
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?

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.
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?
View 1 RepliesI 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

View 1 RepliesI have created a web user control. It contains a table that has several image buttons. I want them to behave link a tab control. Here's the souce view:
Code:
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="ProcessMenuContrl.ascx.vb" Inherits="ProcessMenuContrl" %>
<table >

From another page, I have placed this user control into the main content of the form. I have registered it at the top of the page:
Code:
<%@ Register src="ProcessMenuContrl.ascx" tagname="ProcessMenuContrl" tagprefix="uc1" %>
Here's portion of the source where you can see the control is placed under the MainContent of the page. :
Code:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
<link href="Styles/QuoteStyles.css" rel="stylesheet" type="text/css" />
<uc1:ProcessMenuContrl ID="ProcessMenuContrl1" imgOrderInformation="" runat="server" />
When the user saves information that's on a form from this same page, I want to enable one of the image buttons (imgOrderInformation).
The problem is that i don't know how to reference this image button that's on the user control.

I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
I am stuck into a problem, i have a user control ProductListing.ascx that contains ListView binded to an object datasource, SelectMethod and SelectCountmethod are provided as well. Everything works fine but the problem started when i add another user control declarativlly Filter.ascx in the productListing.ascx. I want to assign value to a public property MaxPrice in Filter.ascx. I am trying to set this property in the SelectMethod of ObjectDataSource. Usercontrol "Filter.ascx" throws null reference exception when i try to set its MaxPrice Property.
I tried to acced the usercontrol in Databind method of ListView , it is accessible here but viewstate is empty at this point, i saved the value in viewstate in SelectMethod of objectDatasource but i cant access viewstate in ListView Databind. Its empty. Its a simple code and no rewriting to viewstate elsewhere.
Important: My Codebehind files are in a seperate project and .ascx files in seperate project

If it is not an element of the Datalist item it would not even enter the loop. I' m lost and unable to find the reason.

When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file.
Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code.
