When HTTP server responds, it includes a status code in a response line. The BIG-IP system may handle a response in various way depending on a status code. If a code is unknown, the BIG-IP system may improperly handle the response.


A response can be improperly handled, and a web page can be rendered incorrectly or not be served at all.


-- A virtual server is configured with HTTP profile. -- Another HTTP-based is in use or an iRule is looking for HTTP::status.
