Questions about Setup

Hello!

I just started to look into varnish. We want to use it with TYPO3 as varnish
seems to be quite powerfull.

I have some question about the initial setup and hope to can shed some light
on me.

As far as i understood varnish can bei used in different setups:

A) On a single Server. Listening on Port 80 forwarding to localhost on a
special port.

B) On a server forwarding to different backends.

My Question, as I did not really understand the vcl conf stuff, can someone
post his vcl conf with some more explanations for one of the mentioned
szenarios.

Thanks a lot in advance.

Olivier

PS: Does anyone a working binary for macos x.. But that is different story
for now.

You can make varnish listen on any port you want really, but port 80 will obviously be the right one for most cases.
Varnish can forward to any number of backends, be it localhost or any other server (doesn't matter too much for Varnish).

In my case we have two varnish front end servers that each hand off requests to one of two backend servers. (The reason for having two varnish servers is simply fail-over considerations, from my observations one of them could easily handle all of the load by itself.)

Maybe it would be better if you asked questions about the things you do not understand? Our config is mainly the normal config, add the backend block, and some specific exceptions for site urls we are sure we do not want cached in any way.

I meant that it would be nice to have some Example Config for us newbies...

The example you are looking for, is the default VCL code which is used if
you don't specify your own VCL code.

Right now, that is not obviously available, but look in bin/varnishd/mgt_vcc.c

Actually, it is reproduced in full in the man page, which also has
examples of useful non-default configurations.
