[OpenLayers-Users] getFeatureInfo errors

[Alessandro Ferrucci]

Maybe this is a dumb question but how do people manage this in production?
I looked at this web site:
http://taossa.com/index.php/2007/02/08/same-origin-policy/ that says that
the policy looks at the port number.  Right now I have my geoserver instance
on the below server at port 8080 and my webapp serving the geo web pages
sits on the same host on port 8082.  I eventually want to have my geoserver
on one machine and my webserver serving up the webpages on a different
machine, I can't see how I can do this given this policy (I don't see the
proxy script as a production solution).

thanks,

Alessandro Ferrucci
