the purpose of this HttpModule? It's showing up on my HttpModuleCollection list, but I don't know what's it's for.System.ServiceModel.Activation.HttpModule
View 3 RepliesI've run into a problem with WCF REST Service. I get:
Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
when running inside of the IIS in an ASP.NET 4.0 AppPool.
The problem seems to occur only if:Running inside of IIS
When ASP.NET Comaptibility is enabled
Running in Cassini - no problem it works properly. Running with ASP.NET compatibility off - no problem it works.
It appears that it's some sort of handler version conflict trying to instantiate the wrong version of the handler that in turn tries to load an older version of System.ServiceModel, but I haven't been able to trace this down.
Anybody seen anything like this before and have any ideas how to track this down further?
I've looked in ApplicationHost.config and the master web.config files for System.ServiceModel and HttpHandler references but no luck.
why this error is coming...this error is cmng after i have re-installed VS 2005 and its framework.

As i know that asp.net fulfill all the requirements for any web application but what are the ground rules for creating custom httphandler and httpmodule in asp.net.Edit:For example I want to fetch image from database then what i should i use httphandler or normally read image from database.If httphandler then why?

It's able to intercept and compress js and css in the development web server but when i run it from IIS 5.1 it is not able to compress js and css files.
Does the order of httpmodule execution match their order in the web.config or is it undefinied?
View 1 RepliesI have custom redirection implemented in a module. Do I have to modify each config for all sites or is there a more general approach?Also, I have files in App_Data for this module, which would cause replication.
View 1 RepliesI'm implementing a simple HttpModule, where I want some code to run when the web application is started. But I'm surprised to find that the Application_Start event I would normally use from Global.asax is not available from a HttpModule. Is that correct, or am I missing something here?
How do I hook into the Application_Start event from an HttpModule?
I'm considering making use of an HttpModule for localization purposes (based on the example in this article) - but I'm curious, is this safe?
Here's the code, for reference:

I was under the impression that multiple threads could potentially service a web request. Is it safe to set the Current/Current UI Cultures in an HttpModule like this and have it respected for the life of the web request regardless of how many threads are involved in servicing it?
I am trying to implement a custom HTTPModule for ASP.NET. I have a very simple html page with an image in it and an HTTPModule that hooks into the BeginRequest event. When I debug with Visual Studio's dev web server, my module is called twice: one for the initial page request, then once for the image request. This is what I expected. However, when I deploy my application to IIS, the module is only being called once for the page request.

View 1 RepliesI want to save each request to the website. In general I want to include the following information: User IP, The web site url, user-if-exist, date-time. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.

I could use late events such as EndRequest and put inside Response.Write but this way whatever I'm adding would come after the /html tag and the HTML won't be well formed.
View 1 RepliesI want to increase the security of my website, does creating http module that block certain ip address will increase security?
Since IP Address can be manipulated if I'm not mistaken, I'm not sure that creating HTTP Module will help.
I have an HttpModule and I'd like to choose the HttpHandler for the current request, is that possible? Also web.config is not an option because the condition is not based on path or extension. My googling skills have failed me, no matter what keywords I use all the results are "IHttpHandler vs IHttpModule".

the title says it all but just to elaborate a little further...What I basically need is to manage a large set of URL rewrites and redirects. The redirects are easy to do but the rewrites should be proxyed through the ARR proxy in IIS. As far as I can tell the IIS rewrite module uses the native setUrl API in IIS to get the ARR proxy to forward the request. I'm not up to the task of writing a native module so I thought it might be possible to write a managed module to do the same.@CarlosAg: Just to expand my comment on your answer. Heres the rules and providers I need to set up to make the rewrite module do what I want. Is it just me or doesn't it seem a little like manipulating the rewrite module into doing something it wasn't supposed to do?

I have an HttpModule which is used to dynamically compress content from an ASP.NET (MVC3) web application. The approach is very similar to the CompressionModule in this article (where the module applies a GZip filter to the HttpResponse and sets the correct Content-encoding header).For one reason and another, this needs to run in classic mode, not integrated pipeline mode.
The problem I've got, is that on some servers that have IIS compression enabled, IIS compresses the content and then my module compresses that. The upshot is that I get content compressed twice, with an encoding:
Content-encoding: gzip,gzip
one from IIS, and one from this line in my code:
httpResponse.AppendHeader("Content-encoding", "gzip");
Does anyone know a way, in classic mode, that I can check to see if the content is already compressed, or if compression is enabled on the server, in order to bypass my own compression?In pipeline mode, this check is as simple as
if (httpResponse.Headers["Content-encoding"]!= null)
{
return;
}
i.e. check if anything has already set a content-encoding and if so, do nothing.However, I'm stumped in classic mode. Unfortunately, accessing HttpResponse.Headers is not allowed in classic mode, so I can't do my barrier check.
My development computer crashed a few weeks back. I took this as the perfect opportunity to upgrade my developmental tools as well as migrate my web app from .net 2 to .net 3.5.My question deals with themes and calling themes from an httpmodule.

Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.
i am making a Website with c# and ASP.NET 3.5, i just made an HttpModule to handle the NHibernate Session Life (Open and close).
I added it to the web.config and everything works fine. (all the query, code, etc working fine) except that CSS file of my masterpage is not loading !!
We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule.
I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this:
protected virtual void BeginRequest(object sender, EventArgs e)
{
Log.Debug("Entered BeginRequest...");
var app = HttpContext.Current.Application;
var hasBeenSet app["HasBeenExecuted"] == null ? false : true;
if(!hasBeenSet)
{
app.Lock();
// ... do app level code
app.Add("HasBeenExecuted", true);
app.Unlock();
}
// do regular begin request stuff ...
}
But this just doesn't smell well to me.
What is the best way to invoke some application begin logic without having a global.asax?
