HTTP port and Ip , its unique identification.

I have Concept related doubt.

Http has port no. 80, at server side request will identify uniquely by (ip+port no).

Now i have open google chrome or any browser , i open 2 tab i request 2 different web page ,how server identify uniquely that this tab has requested this page?

The new tab typically creates a new TCP connection to the server which means new process(or thread depends upon implementation) will be invoked ( new port numbers) .. for ex- if 1st tab is using port no. 54321 other tab will use different port no. ( say 54322).Thus server can uniquely identify a new tab.
