can anybody let me know why the session id changes for first url request in python used on apache? eg: basically request www.mysite.com ,i recieve sessionid=abcd later for next url request like www.mysite.com/something i recieve sessionid=efgh

just due to i cant login to this site since i have try getting session from session table and it is giving error.

In django development server its working fine,nevertheless its leading to error only in apache server.
