[thelist] Hide my location?

I am working on a CGI system which has a robot-like feature.  Our CGI
queries certain sites to obtain certain data.  We have permission from all
the sites but one.  Why not that one I don't know--I didn't ask the client.

He wants to know, however, if there is any way to hide the IP address of our
queries to that site so that they shouldn't notice if we do too many page
requests and upset them.

Thanks,
Hershel
