Apache Web Server Config

Hi Gurus

I am a newbie in Apache.

I want to configure Apache Web server(A for reference) to receive all requests on Port-843 to be redirected to another Apache web server(B) and access a crossdomain.xml(located in /var/www/html) file there.

I have put the following entries in /etc/httpd/conf/http.conf file of Apache server-A:

 
# Ensure that Apache listens on port 843
Listen 843
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:843
<VirtualHost *:843>
DocumentRoot /var/www/html
ServerName <Server B>
</VirtualHost>
 

I have put the crossdomain file in Server-B in /var/www/html.
Is this fine?

Thanks
HG
