Subject Re: [users@httpd] alias using Virtual host
Date Tue, 28 Apr 2009 07:02:26 GMT

Hi,

Let me clarify more:

I have the main http.conf file and created another http.conf to run another apache instance
on port 8094.

I then created a DNS alias (let’s say called alias2) and put these lines

NameVirtualHost *:80

<VirtualHost *:80>
        ServerName alias2
        ProxyPass / http://localhost: 8094/
        ProxyPassReverse / http://localhost: 8094/
</VirtualHost>


This previously worked like a charm on a server where apache was running on port 80.

I suspect that this time, the aliasing is not working perhaps because apache has:

Listen 8088 and
Listen 80

In the config file.

This is the only difference.


With the configuration above, on the current system, http://host and http://alias2 go to http://host:8094
while I want only http://alias2 to go to http://host:8094.

To note that http://host and http://host:8088 refer to the same page

thanks,
