The reason your redirection fails when you set the cookie, is that the location redirection is an HTTP message, but you've printed the header to set the cookie; so the rest of your message is interpreted as text.
kutsu's fix works because it sets the cookie and redirects in a single command.
If the main page and the location-setting page are in the same domain, I believe the cookie will be sent from the client, automatically with each request. You might have to specify the domain explicitly when you create the cookie, as in kutsu's example, depending on the URLs of the main and location pages.

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).
