Apache proxy -- what port?
 

I have Apache 2.0 working fine as a web server. I want to use it as a proxy server also. The configuration looks simple enough. I have loaded the proxy modules. However, when I try to configure my browser to use the proxy, I realize I don't know what port to use? I have tried various ports including the "Listen" ports -- nothing works. I have tried the AllowCONNECT directive (it at least mentions ports), but I don't think that's what I need (or is it?). Here are the relevant lines from httpd.conf:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so

<IfModule mod_proxy.c>
ProxyRequests On

<Proxy *>
Order deny,allow
Deny from all
Allow from 192.168 {i've also tried "all" here -- no difference}
</Proxy>

ProxyVia Off

</IfModule>

So, what port is the default proxy port? (or do I somehow define that?). And how do I override that default port?

Did I miss something in my configuration?

Notes:

- I am remembering to restart the httpd service after modifying httpd.conf.
- Please don't suggest I use Squid. I may try that later, but for now I want to try Apache proxy since I'm already using Apache as a webserver (keeps my life simple).

Thanks!
