Issue/Introduction:

You would like to know the limitations on HTTP request headers on the ProxySG or Advanced Secure Gateway (ASG) appliance.

Resolution:

For versions earlier than SGOS 6.6, the maximum size for an HTTP request header is 8KB. For SGOS 6.6, the maximum size is 128KB. There is also a limit of 125 request headers. So, if the HTTP request exceeds 125 request headers OR 128KB, the request will be denied.
