A session is a store of data on the server containing state information on a user. A particular sessions is identified by its session id, ideally a large (i.e. unguessable) random number. For example, the session could hold a user's shopping cart.
A cookie is also a store. To create a cookie, the server sends a HTTP header to the client (i.e. the web browser). If the client supports and accepts the cookie, the cookie will be sent back to the server along with every request made to the server.
Cookies are often used to store a session id, binding the session to 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).
