title: How to set a rewrite rule in Charles Proxy, when there is a '?' included?
body: <p>I am using Chales Proxy, and it helped me a lot so far. For testing, I use the rewrite rule to change the Path parameters. This works pretty well, as long as I do not try to set the rewrite rule on a a Path which includes a question mark:</p>
  
  <p><strong>Type:</strong> Path</p>
  
  <p><strong>URL sample:</strong> /get/article/123456/n/20121208/?</p>
  
  <p><strong>Rewrite rule:</strong> /? -> /showAdmin=true/?</p>
  
  <p>My guess is that the questionmark is a placeholder, which I can not use as a match value. I tried to escape it, but it did not work either.</p>
  
  <p>Has anybody got an idea how I can work around it? A hint how to work with regEx in Charles would also help. The path is always the same.</p>
  
  <p>Best,
  Klaas</p>
