It occurs when the server tries to redirect without returning a page, but by returning a 302 and a new path in the location header. ---- Sample Result ---- Thread Name: 5.Logins 1-1 Sample Start: 2007-09-06 07:37:33 BST Load time: 234 Size in bytes: 0 Response code: 302 Response message: null Response headers: HTTP/1.1 302 Date: Thu, 06 Sep 2007 06:39:45 GMT Server: Apache Set-Cookie: ..........
