title: URL Rewriting/Redirects with Querystring?
body: <p>We have a situation where I have a bunch of urls with query params that are used to bascially redirect to various sites, kind of like a short URL or index.</p>
  
  <p>Ex: www.mysite.com/abc?x=123   which redirects to www.google.com
  www.mysite.com/abc?x=456   which redirects to www.yahoo.com
  and so on...</p>
  
  <p>The issue is that there isn't an actual page "abc" now or prior, these links were created and published unknown to the site.  The issue is now finding a simple means to make them active so when clicked will do the proper redirects.</p>
  
  <p>This is currently on an IIS Windows server.  The core site itself is .NET based.</p>
  
  <p>Is there a way using an htaccess file or similar (assuming we use a mod-rewrite isapi plugin for IIS) to allow creating these redirects?  We have hundreds of these to create.</p>
  
  <p>The only other option I can think is redirecting these in turn to an actual asp.net page which would then process the param and redirect logic in code, assumign we can do a rredirect from the base URL to a real page easily.</p>
  
  <p>The real problem I guess is getting around delaing with "abc?x=456" when there is no actual page in existence and no extension is given anyway to put a page in place.</p>
