An easy way would be saving the remote IP together with browser signature inside the session, and rejecting any request not matching the stored info
The client's IP often changes in between requests. If the client's ISP is using a rotating proxy (which many big ISPs do), this is so common that it renders this approach unusable.
There is no 100% secure and browser-independent way to prevent a stolen cookie being replayed by the thief, impersonating the user.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
