[PHP-DB] How can you include an https?

[Camelia Enderby]

Hi guys,
Just stumble on this problem. I need to be able to include a file from another server 
into one of my script. Not to difficult except that the file is on a secure server and 
it doesn't seem to work.
Anybody knows of a way around.
I have php 4 running on Red Hat with mysql databse.
Thanks in advance
Cami
