How can we identify that the Page is Post Back?

please if any one having this answer please tell me

I will make a guess
Are you asking how you can know when a person replies to something that you write here? There is no notification. You need to look and see.

I assume that English is not your first language. I had to guess about the meaning of your question. If I was wrong about what you asked, I tried.

my guess
Mu guess is that he is looking fora way to use backwards links from here to promote his web site. I am thinking the term he wanted is track pack, not post back.
