While using sessions, if the browser's back button is clicked the page expires. How to avoid this?

Short answer: Don't use POST. This is not related to sessions

When you use the POST method (i.e. a form), the browser doesn't re-post
the data every time the page is refreshed to prevent things like doing
an online purchase twice.

I can't tell from your question, but it may be that the page is expiring
from the cache. If this is the case, use the header() command to set the
cache.
