Friends:
When you put a object in the session, does that mean the whole object is
loaded in the memory. 

Because if the whole object is stored in the memory, then the chances of
reaching the peak and getting out of memory errors are high.

Example: Say I have a image and I need to put that in the session. Does that
mean the whole Image object gets stored in the memory for each session
created. 

Or is it that only the reference to the object is loaded in the memory.

Best Regards
Gunjan
