SGOS 6.5.x and older versions, HTTP debug can not be filtered with specific client machine IP or server IP. On a busy proxy appliance where HTTP debug can not be filtered, it is recommend to take the http debug within a short time window by reproducing the problem or take the HTTP debug during off hours when the appliance has minimal user traffic.
Starting with SGOS 6.6.x and later HTTP debug can be filtered with specific client machine IP or server IP. To apply this filter navigate to http debug URL of your proxy.
To apply specific client IP or server IP filter select Debug filter(s).
