Application.EndRequest, MVC and .htm files

Question

I have the following code in my Global.asax:

void Application_EndRequest(object sender, EventArgs e)
{
    HttpApplication application = sender as HttpApplication;
    HttpContext context = application.Context;
    string path = context.Request.Path;
    string contentType = context.Response.ContentType;

    System.Diagnostics.Debug.WriteLine("-----------------------------------");
    System.Diagnostics.Debug.WriteLine("Path: " + path);
    System.Diagnostics.Debug.WriteLine("ContentType:" + contentType);    
}

I have a Help folder at the root of the site (~/Help) that contains static .htm files. I notice that not all of these files are being run through EndRequest. Sometimes I see assets in the page being logged (e.g. .js files) but not the htm file itself. Sometimes they do get logged.

Why don't all of these files run through EndRequest and how can I ensure that they do?

Answer 1

In the end my configuration is like this:

• AppPool pipeline: Integrated
• RouteExistingFiles: false (default)
• runAllManagedModulesForAllRequests: true

All of this was how it was when I wrote up this question. The thing I did different was to go into my web.config and manually add a handler under <httpHandlers>:

<add verb="GET,HEAD,POST,DEBUG" path="*.htm" type="System.Web.UI.PageHandlerFactory" />

One thing that was throwing me off was that once the file had come down the browser was caching it and not re-requesting it (until I cleared the cache).
