Hi
As i remember when we do the dynamic webpage with php, the address of the page is usually look like this
http://www.domain-name.com/r.php?bar=foo&req=home

but now when i see webpages that are written in php (At least part of it) they have address look like this:
 http://www.domain-name.com/r.php?bar=foo&req
which req is variable and should have value like bar=foo
The good example is facebook.com which when you try to upload your image the address is look like this
upload.facebook.com?upload

I just want to know dose anybody know what is behind those kind of urls?

Thanks

nothing it is an unset variable if its normal php
but if u have set some stuff under the server running it can mean that it gives the command to upload(in this case)
