IIS7 Application Request Routing (arr reverse proxy) combined with managed module - time out

Question

I am trying to build a proxy that would serve requests to an internal site (hiding the origin) but at the same time inspect the packets and asynchronously post-process them.

If you can switch to .Net Framework 4, there is a solution for this.

After you are done with your BeginRequest/EndRequest in your HttpModule event handler, add a call to HttpRequest.InsertEntityBody.

    /* BeginRequest event: Executes before request is processed */
    private void Application_BeginRequest(Object source, EventArgs e)
    {
        HttpApplication application = (HttpApplication)source;
        HttpRequest request = application.Context.Request;

        // Do something with request
        DoMyOwnRequestProcessing(request);

        // After you finish, make sure IIS gets the entity body
        // For example, Application Request Routing needs this
        request.InsertEntityBody();
    }

Take a look at this on MSDN: HttpRequest.InsertEntityBody.
