Thread:Project:Support desk/Colons converting to in URLs -- fix?

Hi all-

I'm running a test installation of our wiki upgrade (moving from Windows Server 2003/IIS 6 to Windows Server 2008(x64)/IIS 7.0). I noticed that in all the URLs within the wiki, the colon symbol is converted to %3A. Fortunately, if someone links to a page outside the wiki with the colon in the URL (for example, /index.php?title=Special:SpecialPages), it still works (and the URL remains unchanged in the address field). However, perfectionist that I am, would prefer to have the colons back since having %3A in links looks so... ugly.

I've been fiddling around with the URL rewrite module in IIS but have been unsuccessful in getting the links to convert back to using colons. Have tried following some of the guidelines on Manual:Short URL/IIS7, but seeing as we're NOT using short URLs (and would like to keep it that way), the instructions don't exactly apply.

In my noob attempt at changing the rewrite, I tried using this in my web.config file -- basically I *thought* it was telling it to replace any %3A URLs with ":", but it doesn't seem to be the case.

Any insight/help would be much appreciated -- thanks!
