Enabling httpd_accel_port virtual mode enables port-based virtual hosts. > do i have to change it to the port of the web-server? This is required. These directives control how Squid reconstructs the complete requested URL on accelerated requests httpd_accel_uses_host_header tells Squid to use the Host header of the request if available. httpd_accel_host tells what host name to use if httpd_accel_uses_host_header is not enabled or if the request does not have a Host header. httpd_accel_port tells what port to use in the reconstructed url. If 0 then the port number of the http_port will be used. So if you have http_accel_host virtual http_accel_port 0 http_accel_uses_host_header off (or request without Host header) http_port 1.2.3.4:8888 then the URL as seen by Squid will become http://1.2.3.4:8888/path/to/file and this is the URL Squid will try to retreive, which most likely is not what you want unless you are using a redirector to fix up this URL into something which makes sense. The recommended accelerator setup for Squid-2.5 is # Host to assume if there is no Host header httpd_accel_host your.main.domain.name # Normal web port httpd_accel_port 80 # Domain based virtual host support httpd_accel_uses_host_header on # Required for RFC compliance httpd_accel_with_proxy on Then add the accelerated hostnames to /etc/hosts with the addresses of the real web servers, and configure Squid access controls to limit what may be accessed # Base ACLs acl all src 0.0.0.0/0 acl port80 port 80 acl http proto http # Give access only to our accelerated servers acl ourwebsites dstdomain accelerated.web.name other.accelerated.web.name http_access allow http port80 ourwebsites # Deny all other uses http_access deny all For Squid-3 the setup is a little different, but Squid-3.0 is not yet released so more on that later.
