Setting referring IP address

[kdoggy]

I was wondering how I would use PHP to set the reffering IP address? I know how to set the reffering browser by ini_set('user_agent','PHP'); Can I do the same thing for the IP address?

I am using a PHP script to fetch a text file off another server but the way I have the server set up it will not accept a request from a referring IP other than itself.

Please let me know if there is any way to do this.

the ip is identified from the tcp packets the server receives so its not possible to change it, unless you want all the data sent back to the wrong place, but then its still not possible with php and you'd have to use a language like c to construct the packets. isnt it easier to just modify the recipient server to add your new ip to the access list.
