opening a file from another SD card on another Arduino


Is there any way I can open a .txt file allocated on an SD card from another Arduino?

I have 2 Arduinos. One with one SD the other without. The arduino with SD should work as a server, so that later I could access the information from within this .txt on the other arduino through a GET command.

I tried to use the GET command to get the FILE.txt on the client, but I could not. Can anyone give me a light? or at least say whether this is possible or not.
