Early HTTP response from the server might cause 'server drained' assertion and traffic disruption.
The system posts a 'server drained' assertion and traffic is disrupted.
This occurs when the server sends an early response, which might occur if the server responded before the system completed processing the entire incoming HTTP request data from the client. A filter other than HTTP is also required on the chain.
None, however, this issue occurs very rarely.
HTTP will not cause a "server drained" assertion if a server ends a connection in an early server response.
