Apache HTTPD.config port translation

What settings would I need to change in the apache httpd.config file to
have apache translate web requests targeted at port 8888 to port 5555?

The httpd.config file has settings for a Virtual Host and settings for
a Proxy Server. Which would be better to use for such a port
translation?

thanks in advance, Andy

About...

You should use something else, like a simple iptable rule (why use
a bulldozer to move an apple?). But from what you said it seems that
you
need to use the VHost after allowing Apache to listen on port 8888.

I'll look into iptable rules...thanks for your suggestion!
