Hi,
I'm going to use squid as a reverse proxy.
There's one machine, that's visible in the internet: 192.168.1.100.
Incoming requests on port 80 from the internet are forwarded by the
router to this machine. On this machine I am running squid, which also
listens on port 80.
The machine, that is running the webserer is 192.168.1.98 (also on Port 80).
In my squid.conf on 192.168.1.100 I have set the httpd_accel_host to
192.168.1.98 an httpd_accel_port to 80, which says "forward all requests
on port 80 to the machine 192.168.1.98:80.
When I enter our url (http://ourname.dyndns.org/ or
http://<our-ip-address>/ ) in a webbrowser, which is running on machine
in the internet, we get the apache test page, which is configured with
fedora's apache installation. Thus our forwarding seems to work.
But when I enter our url in this way: http://ourname.dyndns.org/ourcms,
it's not the proxy that answers the request, but the browser tries to
contact the webserver 192.168.1.98 directly, which is of course not
visible in the internet.
When I enter an invalid url like
http://ourname.dyndns.org/asfddkfljghdsf, I receive an 404 "not found"
error as expected.
Contacting the webserver directly is definitely not what a reverse proxy
is made for!?
What can I do?
thanks and greets
Boris
P.S. I'm attaching our squid.conf:
