Hi all, I'm running squid/2.6.STABLE21 behind an SSL offload appliance on port 8443 as an application accelerator. squid.conf: http_port 10.67.124.57:80 accel vhost protocol=http http_port 10.67.124.57:8443 accel vhost protocol=http cache_peer 127.0.0.1 Parent 80 0 no-query no-digest default login=PASS originserver It's rewriting the Host header of requests and adding the port number to the URL, eg. Host: myvhostname.com:8443. This is breaking the app behind it. Note, url_rewrite_host_header is set to off. Any ideas what's causing this behaviour? It's only happening in our QA env and is working fine in PROD with an identical squid version and config. Regards, Sean. This e-mail is confidential.
