title: IIS 7.5 Rewrite Bug? Infinite loop
body: <p>We use IIS 7.5 URL Rewrite, with classic ASP.  Everything works properly 99% of the time, however, completely sporadic, pages of our site will fall into a redirect loop for no apparent reason.</p>
  
  <p>Meaning, we have articles that render fine 99% of the time, but, like this morning, when accessing one article (out of thousands) the browser will respond with a "The page is not redirecting properly".  I use Firefox, but this occurs for all users in all browsers.  This also occurs on the site home page, and other pages, sporadically as well, so it doesn't appear to be related to a specific rewrite rule pattern, rather the rewrite rule engine as a whole.</p>
  
  <p>Resetting IIS solves the problem immediately, and the page(s) load fine.  Resetting IIS seems to be the only way to fix this problem when it occurs.</p>
  
  <p>IIS logs show 301 redirects for whatever page is affected.  In this case, one article page had thousands of 301 redirect log records.  Resetting IIS corrected the behavior.</p>
  
  <p>Has anyone else had this issue, or any ideas on how to resolve?</p>
