How to stop IIS from decoding URL [duplicate]

Question

I use windows 7, IIS 7.5, .NET 4.5.
(For windows 8, IIS 8.5, .NET 4.5, this works).

performing a GET request with URL:

http://my.host/api1/MyEntity('%2311282')

Problem is that when it gets to servers side code the %23 char is already decoded to '#' and Uri object thinks it is a fragment char. Win8 machine receives the url with char %23 untouched.

Tried to:
1) use this config setting

<httpRuntime targetFramework="4.5" relaxedUrlToFileSystemMapping="true" />

2) add '/' in the end of the URL

http://my.host/api1/MyEntity('%2311282')/

3) uninstall the url rewrite 2 module - and reinstall it. also tried to comment the rewrite section in web.config for the module.

Why I want to replicate windows 8 behavior - not decoding the URL. Any ideas?

Answer 1

Take a look into Rewrite Module.

some information here: PRESERVING ORIGINAL URL

The URL Rewrite Module preserves the original requested URL path in the following server variables:

HTTP_X_ORIGINAL_URL – this server variable contains the original URL in decoded format; UNENCODED_URL – this server variable contains the original URL exactly as it was requested by a Web client, with all original encoding preserved.

hope that helps.
