title: IIS URL Rewrite For URL Link with %3D
body: <p>I am having an issue where someone has posted a URL for my asp.net mvc3 site that contains %3D instead of an equal sign after my id parameter like this: <a href="http://ultimategamedb.com/Article/Article?id%3D398210c1-529e-4909-9793-a11b8a832dcc" rel="nofollow">http://ultimategamedb.com/Article/Article?id%3D398210c1-529e-4909-9793-a11b8a832dcc</a> .  I have tried various rewrite rules but cannot seem the URL to rewrite correctly to: <a href="http://ultimategamedb.com/Article/Article?id=398210c1-529e-4909-9793-a11b8a832dcc" rel="nofollow">http://ultimategamedb.com/Article/Article?id=398210c1-529e-4909-9793-a11b8a832dcc</a> .  It is a problem because the URL with the %3D gives a 404 error.  If possible I would like to create a rule that rewrite any URL with % encoding to the correct decoded values.  If this is not possible I would just like to know how to rewrite my article URLs to ensure that a %3D will never show up for the equals sign in an Article URL again.  </p>
  
  <p>Could anyone explain to me how I would go about creating these rewrite rules?  Thanks in advance!</p>
