/*This function is used on Ajax functions to handle errors for onFailure and onXYZ
Currently all application exceptions are handled by the global exception handler (in global.asx)
The 550 error is an OLC custom error status to describe a session timeout.  There is code in the 
controlhandler.aspx.cs that checks to see if the session has expired, and if so sets the response
statusCode to 550.
