Severity: 4-Minor


The BIG-IP system might close a connection when the HTTP response payload is modified and sent without chunking encoding. If communication goes over an HTTP connection, the BIG-IP system closes a connection to tell a client that a response is served. With HTTP/2 connections, an unsized response is marked with the END_STREAM flag. This case is not accounted for, and the BIG-IP system closes HTTP communication with a server anyway.


The BIG-IP system wastes resources not reusing a server side HTTP connection when an unsized response is sent over an HTTP/2 connection to a client.


-- A virtual server has an http/2 profile configured on the client side. -- There are other profiles configured which can modify the HTTP response payload.
