When you use the 'HTTP::disable discard' command in an irule to switch to HTTP transparent passthrough mode, the proxy connect / connection to server is not established. This only occurs when the 'HTTP::disable' command is used with the additional 'discard' option (which discards the existing HTTP headers before switching to passthrough mode) Refer https://clouddocs.f5.com/api/irules/HTTP__disable.html
Client requests containing the HTTP CONNECT method hang (data is not proxied to the serverside flow)
-> Basic HTTP VS -> iRule when HTTP_REQUEST { HTTP::disable discard node <ip port> }
Use 'HTTP::disable' command (without the 'discard' option)
None
