title: Regex to match strings containing "+" in IIS URL Rewrite Module
body: <p>I have a bunch of url's that I would like to rewrite in my IIS with the URL Rewrite module.
  The urls looks like this: <code>http://domain.com/randomstring+endrandomstring</code>. The catch here is the "+" sign. It ruins everything.</p>
  
  <p>I've tried to match it with following regex, and even though the module says that my urls are a match, it doesn't redirect when I try it live in a browser: Regex: <code>randomstring\+endrandomstring</code>.
  I've tried grouping, end ($) and beginning (^). All which the module accepts as a match but doesn't work live. Also tried with the url encoded version <code>%2B</code>. No luck.</p>
  
  <p>Does the "+" sign have some kindda wierd url formatting or maybe its reserved character of some kind? </p>
  
  <p>The "test pattern" function in the module accepts my regex as a match: </p>
