title: Updating/Intercepting HttpContext.Current.Request.QueryString
body: <p>Here's a wierd one. I'm reusing a code base that unfortunately must not be updated. This code makes a call to <code>HttpContext.Current.Request.QueryString</code>. Ideally, I need to push a value into this collection with every request that is made. Is this possible - perhaps in an HTTP Module?</p>
