Why does Cassini treat URI:s with multiple slashes as a Bad Request?

I am struggling to get similar behaviour from my dev webserver [1] and my test environment [2], and am now looking at why the dev returns HTTP 400 Bad Request with this URI?

http://localhost:1234/v1//Dy888/1/1234567815/swlocation?fv=24&sv2=3&sv3=5

(Note the two slashes after "v1".)

[1] Cassini in VS2008 [2] Win Server 2008 with IIS7

Thanks in advance! - Niklas

PS. I started this search with this question, where I was told that the URI aforementioned should not generate a Bad Request at all:

IIS7 NOT returning HTTP 400 for a bad request DS.

You should not expect similar behavior between the ASP.NET Development Server that comes built-into Visual Studio and the IIS Web Server.

They are generally two different web servers with different code bases and different feature sets. Even if they should behave similar (what they definitely don't e.g. web server features like SSL, URL Rewrite Rules, etc.) never expect them to do so.

That's just another reason Microsoft stopped the development for the ASP.NET Development Server and introduced IIS Express to get your development and your production web server experience again on the same page.

So my recommendation for you is:

  • Stop using the ASP.NET Development Server
  • Start using IIS Express
  • Still don't expect them to behave the same!
    In question only a test/staging system running a real IIS instance can give you the real experience!

Hope that helps!
