title: How can I access the request body in an IIS rewrite provider?
body: <p>I've written a custom rewrite provider using the <a href="http://www.iis.net/learn/extensions/url-rewrite-module/developing-a-custom-rewrite-provider-for-url-rewrite-module" rel="nofollow"><code>IRewriteProvider</code> interface</a>, and installed it in IIS.  It's working, but I need to access the content of the <em>request</em> as well as the URL.  A <a href="https://groups.google.com/d/msg/urlrewritingnet/cVNupSKPlzE/ucdwQBjmOh0J" rel="nofollow">newsgroup posting</a> suggests that I should be able to access <code>HttpContext.Current</code>, but in my testing it shows up as <strong>null</strong>.</p>
  
  <p>Is there any way to get access to the request content from a rewrite provider?</p>
