Actually using javascript it is possible although probably not
recommended and again can not be guaranteed to work on all browsers.

Is there any browser that sends a signal to your server when a user
clicks
the back button? Or is there any client side script that can detect this
for
you?

The answer to the first question is: No.
The answer to the second question is as far as I am aware: No.

So that means that the answer to your question is unfortunately: No.

What you might be able to so is keep track of where the user was last in
the
session, and then on the page that they navigate to take an action based
on
the location they came from, btu that can quite quickly become messy as
a
user might type a URL directly which might mean the new page is not the
previous page but four pages back or a completely different unrelated
page.

You could also consider that if you need to take an action based on the
back
button then you need to alter your design since this should not be
needed,
looking at al kinds of web tool kits using ajax and other "cool" words.
You
can see many examples of frameworks that manage to handle the back
button
gracefully, even though most web developers will tell you that the back
button is the one thing that all browsers have and that is just as hard
to
code for in every single one of them.
