Description

When trying to setup Gitea on a Windows Server 2019 with IIS using the reverse proxy configuration example from the official documentation, pull requests won't work at all. Server is returning 400.

This is due to some weird IIS specifics, they don't allow to use some special characters in the URL by default.

Fix

Adding this to the config fixes the pull requests:

<system.web>
    <httpRuntime requestPathInvalidCharacters="" />
</system.web>

I'll create a pull request for this issue.
