ASP.Net URL Encoding

I am implementing URL rewriting in ASP.net and my URLs are causing me problems.

The URL is generated from a database of departments and categories. I want employees to be able to add items to the database with any special characters, without having to break the site.

I encode the data before creating the urls.

There are a few problems ...

  • IIS decodes the URL before it reaches .net, which makes it impossible to correctly parse anything with an "/" in it.
  • ASP.net is confused that URL makes "~" useless on certain pages
  • I switched from the built-in test server to my local IIS server (XP machine), and any URL containing the encoding, and (% 26) gives me a "bad request" error.
  • UrlEncode leaves some breaking characters intact, such as '.'

I had two more related posts on this subject, while I saw only minor problems, not a big problem upstream. I found some tricks in the registry to solve the "bad request" problem, but I'm going to deploy a shared hosting environment, making it useless. I also know that this is a fix for some security issue, so I don’t want to get around it without knowing what might come from the worms that I open.
