i guess the requested URL is my problem too. let's say the user should =
www.calendar.ca to get to the calendar-server (port 81) and www.mail.ca =
get to the mail-server (port 80).
would the configuration look like this:
build squid with ./configure --disable-internal-dns
http_access allow all # to make it short and simple for this example
httpd_accel_host XXXXXXXXXXXXX # what here? the www.canada.ca
/etc/hosts # at the reverse proxy server
as i sad, the requested URL is my problem. i don't know wich URL i have =
request from a client und by which criteria the reverse-proxy desides =
web-server to use.=20
does the hosts entries must also be mad on the clients, so they don't =
the general DNS-server what ip is behind www.mail.ca=20

The use of different ports in the public URL than what the actual =
runs on is also not recommended, as this often causes problems where =
internal port leaks out to the browsers, often as part of plain normal=20

this is not what you want to use, as explained earlier. You only want =

of this directive absolutely REQUIRES a redirector helper to fix up the =
In all other accelerator setups httpd_accel_host SHOULD be set to your

ok, but you must then use a redirector to rewrite the port to 81 on=20
requests for the calendar server.
The other alternative is to use two http_port directives and virtual=20
this will use whatever http_port the request was accepted on as port=20
number in the requested URL.
