[users@httpd] Proxy on port 80 and 443

[Khoa Nguyen]

I am trying to configure apache 2.0 as a forward proxy server for both port 80 and 443. Below is my config:

AllowCONNECT 80 443

<Proxy *>
    Order deny,allow
    Deny from all
    Allow from 172.16 10
</Proxy>

NameVirtualHost *:80
NameVitualHost *:443

<VirtualHost *:80>
   bla bla bla
</VirtualHost>

<VirtualHost *:443>
   bla bla bla
</VirtualHost>

================

Problem is that the HTTP CONNECT method to <IP Address>:80 works find, but HTTP CONNECT to <IP Address>:443 returns an error message "Your server doesn't understand the request" or something similar. What might be the reason? Is it possible that apache assumes HTTPS on port 443?

Thanks,
Khoa
