HTTP CONNECT request with 4xx response with body results in RST
Connection reset when server responds. The system posts errors similar to the following: -- err tmm3[19210]: 011f0007:3: http_process_state_prepend - Invalid action EV_INGRESS_DATA during ST_HTTP_PREPEND_HEADERS (Server side: vip=/Common/http-vip profile=http pool=/Common/nc-pool server_ip=10.20.142.1) -- err tmm3[19210]: 01230140:3: RST sent from 10.10.147.80:80 to 10.10.132.1:56111, [0x18f7e62:9888] {peer} HTTP Unexpected server data past end of response. -- err tmm3[19210]: 01230140:3: RST sent from 10.20.147.1:56111 to 10.20.142.1:8080, [0x18f7e62:9888] HTTP Unexpected server data past end of response
This occurs when using Content-Length header when the server responds with 4xx response with body for CONNECT request.
Create a iRule to disable HTTP filter when CONNECT method is detected: when HTTP_REQUEST { if { [HTTP::method] eq "CONNECT" } { HTTP::disable } }
The system now honors Content-Length header when server responds with 4xx response with body for CONNECT request.
