I have a site that uses ASP.NET AJAX and web services extensively. I have one user that is unable to use any page that utilizes AJAX/web service calls. I'm thinking that her firewall is stripping required headers off of the request and the result is she is getting error messages that read: "The server method *insert method name* failed.", with a status code of 403 and no exception type. I'm not using UpdatePanels. I'm calling the web services directly from javascript functions.
Has anyone experienced this? Is there a workaround?
