everytime i do a file upload lets say the name of the file upload is img_xxxx.jpg
but another user who is logged in may also upload img_xxxx.jpg and overwrite my
upload because we are sharing the same upload folder.
how do i prevent this problem ? can i like assign a filename which i can tag
the session id to the name of the file that is uploaded by modifying ewupload.cs ?
and this new filename will be saved in the database instead ?
