I am using ngenix + tomcat cofiguration.
I was having a site "domainname.com" hosted by ngnix and running in tomcat.it is running fine.It was running on 80 port in ngenix.
But i was told to run a copy of this site "domainname.com" on 81 port.
So what i did is as follow:-
i deployed the same site in tomcat .
Then in ngenix i copied the old .conf file of "domainname.com" site and created a .conf file to be used for "domainname.com" site on 81 port.
So after restarting the ngenix now when i access the site as "www.domainname.com:81" and log in in to it i am imediatly logged out(same code with www.domainname.com domain on 80 port is running fine but on 81 port this issue is coming. I have got stuck in to this please help me.
