One of my users reports failures where the following is occasionally coming through the AJAX call: "<HTML><HEAD><TITLE>Cisco Systems Inc. Web Authentication Redirect</TI..." My code error_logs this when eval () fails on the JSON data returned through the AJAX call.
This is hard to debug short of visiting the physical scene of the problem. I'm thinking that each chunk of data returned through AJAX ought to have something in the header to mark it as belonging to the application.
