.NET Requests Always BeginRequest And EndRequest On The Same Thread?
Sep 5, 2010
Does BeginRequest and EndRequest for an ASP.NET HttpApplication always occur on the exact same thread for a given HTTP request from a client?The reason I ask is that I am seeing some very strange behavior where a ThreadStatic variable is not null inside of an Init method for an IHttpModule. I set this ThreadStatic variable to a value on BeginRequest and null it on EndRequest.
However, my IHttpModule Init method should be called outside of the BeginRequest/EndRequest period, so the only way I can think of that this ThreadStatic variable would have a value when my Init method is called is if EndRequest occurs on a different thread than BeginRequest and thus the value is still not null later on when ASP .NET tries to use that same thread to create a new HttpApplication instance...
I am running IIS 7 in integrated mode.

Are beginRequest and endRequest working while sending and retrieving data with jquery? In my observation these functions (see below) are not working anymore. Is this because it's not a real postback?
function pageLoad(sender, args) {
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequest);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequest);
}

I'm debugging an ASP.NET MVC 2 application running on .NET 4.0 (Windows 7), currently inside of Cassini, the Visual Studio Debugging Web Server.All was running well, when I suddenly was having exceptions in my Application.EndRequest handler. After investigating into this issue, I found the reason was that Cassini was calling EndRequest on a different thread than BeginRequest (then, a ThreadStatic variable which was set in BeginRequest and used in the EndRequest handler was null, since on this thread, BeginRequest was never called).What could be the reason for Cassini to execute BeginRequest and EndRequest on different threads?I know the reason could be an 'Async' Page directive (see Do ASP.NET Requests always BeginRequest and EndRequest on the same thread? , but I have no 'Async' attribute in my Page directives).

I'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
Here is a quick example of how I use threading:

What's the simplest and most effective way to selectively redirect HTTP requests to your ASP.NET page to its HTTPS equivalent? For example, if my page site URL is [URL], I want to redirect some (or all) page requests to [URL] What's the easiest way to do that?

I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.
# WindowsIdentity = WindowsIdentity.GetCurrent()
which returns the identity of the security context of the currently executing Win32 thread.
# Thread = Thread.CurrentPrincipal
which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.

I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having
bool isGoodPassword = (password == expected_password);
lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.

I have a HttpModule that hooks on the EndRequest Event on a IIS6 with a wildcard handler registered and it works fine as long as the request ends on a .aspx page, but NOT if the url is missing (404).I guess it's because of the staticfilehandler ends the request, but is there any good solution for this problem ?I have tried the same solution in IIS7 (pipeline mode) and there it works fine.

I am writing a quick-and-dirty in-house ASP.NET application that needs to be able to run a task after a specific period of time. If it was a proper application, I'd probably use a windows service but I don't really want to bother with the extra complexity of that.I could put code in the BeginRequest handler to check whether any such tasks are due, but of course nothing would happen if nobody is using the application.at the moment the best option I can think of is something like ShellExecute("nohup sleep 1000; wget http://server/dummypage.aspx") (if you'll excuse the mixed windows/unix nomenclature).

I was under the impression that static files (CSS, images, @font-face files, etc) bypassed ASP.NET completely, and were served directly by IIS. However, my BeginRequest event handler is being called for every HTTP request, including those for static files. This concerns me because I'm creating an Entity Framework data context to be used for the lifetime of each request in that event handler. I don't want to create those contexts if they're never going to be used.
I'm using IIS 7 on Windows 7 Ultimate with so special handler mappings defined. Do I have it wrong? Should these events be firing?

we are having some weird issues with URL Routing in ASP.NET 3.5.
We have a search box that does a search and redirects to a routed URL.
When we search for the first time (aka Press a button that forces a postback) everythign works as expected. we get:
1. BeginRequest event.
2. Determines Route
3. Calls Routehandler to match the route item to the actual destination page
4. Routes the url appropriately.
After you do one search successfully and try again it fails to call the BeginRequest event. Because of this the routing data never gets called and so the url is never routed to its correct destination. What is weirder still if we append a "/" (trailing slash) to the url after the initial postback it DOES work properly again.
So our search route looks like this
mydomain.com/Search
entering a term and pressing the SEARCH button would yield a result url like this:
mydomain.com/Search/Results/MySearchTerm
Going back (after 1 successful search) you then need to use this url or else BeginRequest will never fire:
mydomain.com/Search/ < (note the extra "/" at the end)
why the BeginRequest event never fires unless the slash is appended?

I'm developing IP Blacklisting HttpModule in asp .net application and I found one very annoying thing. Each request to the asp net page generates tens of "subrequests" to application resources like images, client side scripts, styles etc.
Now in my application I'm listing to the BeginRequest event and when it is fired I'm loading Dictionary with blacklisted IPs from application cache and check user's IP against it. I've made a simple log of what is actualy happening during each page view, here are the results:
[Code]....
As you see, one request to Login page causes BeginRequest to fire 18 times, there is 18 dictionary loads, 18 lookups etc. That's not the way I want it to be.
Is there any other event that is raised only once per each request? Where do you place the blacklisting mechanism in your applications? I know I can do it through ISAPI filter, but the catch is, this site is on the shared hosting and I'm not sure I can use it on their IIS. Also I'm not sure if ISAPI filter can access some piece of cache with this blacklist (I don't want to load it from DB on each request, that's obvious).

I'm running VS 2008 and .NET 3.5 SP1.
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.

I need an explanation regarding some advice I got on this site. I'm doing a newsletter sending app, and I have my mail sent in a seperate thread so the process doesn't slow down the whole web site. A couple of people advised me to set the threads IsBackground property to true. I did this, but was also courious about what this does, so I googled a bit.
As it turns out, setting the IsBackground property to true indicates that "it's okay if the process shuts down while this thread is still running.". Or as microsoft puts it "Any remaining background threads are stopped and do not complete." I don't know if I got this the wrong way but, wouldn't it be better to leave the IsBackground property to false, so that the spawned thread can complete its work regarding the main thread?
