Downloading files in php through 2 different servers

[sparky11]

I am totaly at a loss here i dont even know where to begin

How do i download a file in php which is on another server but the kicker is that the person has registered on the main site an I want to redirect the person to the dl site on a different box and have it so that the person does not have to register on the download box also make it so they can not link directly to the download link

any help would be great

I don't know if this is possible through PHP scripting alone,
eg. sessions only work on 1(one) domain

you could check the referer, but it is not so secure,

eg.

check if referer = "your server1"

if true

on DL server that reads the content in the folder,
display it and c

if not true
exit
