[Mapserver-users] Loading data from another server

Ok:

What i'm attempting to do is the following in details:

I have some proprietary data as shape files and i want to allow a client to 
be able to browse my data using his maperver application.

The user (client) is running MapServer3.6 on a Windows machine with Apache 
web server.
My data are located in my web server hosted on a linux machine (apache web 
server).
ex. www.MydataServer.com

Basicaly, i want to keep the data in my web server and allow an external 
mapserver application to browse the shape data and use them in his 
mapserver.

What would i need to do to reach this goal ?

Thanks,

Jeff
