Creating a relay php page

[donbmjr]

Creating a relay php page, there is more than likley a better term,
my apoligies for not knowing what it is.

Is it possible for php to callup a page on another server with
a link, while keeping the URL address of the site hidden,
something like you can with asp.

Example

href="/default.asp?c=testsite&page=/stats/sales_
results_2004.html

I have 3 companies that I will be creating charts in macromedia
flash for, and want to keep the url hidden in the source code.

All of the files, html and flash (swf) will be in an IFrame
Example

<iframe name="statsFrame" src="http://www.testsite.com/stats/jan_sales.swf" frameborder="2" scrolling="auto" align="center" height="600" width="400">
TEXT FOR NON-COMPATIBLE BROWSERS HERE
</iframe>

If necessary I can move all the files to be called up to there own
server, it would be a windows server and the URL would still need to be hidden

Thanks
