I have a backend (application) server that rejects requests that are not HTTP/1.1 (rejected with a "HTTP/1.1 505 HTTP Version Not Supported"). It also requires that connections come in over SSL. I would like to place a Squid instance in accelerator mode in front of this application, but haven't found a way to convince Squid to talk HTTP/1.1 to the backend over SSL. All the requests I see are coming into the backend as HTTP/1.0. Is there a magic recipe to force Squid to use the HTTP/1.1 protocol to the backend? I've tried Squid-3.0-STABLE8 and Squid-3.HEAD-20080909 with no difference. Here's the squid.conf: #-------------------------------------------------- # Squid.conf visible_hostname frontend.mydomain.com httpd_suppress_version_string on http_port 80 accel defaultsite=10.2.3.4 https_port 443 accel defaultsite=10.2.3.4 key=/apps/squid/etc/squid.key cert=/apps/squid/etc/squid.crt cache_peer 10.2.3.4 parent 443 0 no-query originserver name=backendssl ssl sslflags=DONT_VERIFY_PEER proxy-only cache_peer 10.2.3.4 parent 80 0 no-query originserver name=backendhttp proxy-only acl VDI dst 10.2.3.4 http_access allow all cache_peer_access backendssl allow all cache_peer_access backendhttp allow all request_body_max_size 0 # Debugging: debug_options ALL,9 error_directory /apps/squid-3.HEAD-20080909/share/errors/en Thanks, --Joe
