Session ID Cookie or a Session ID Hidden Form Field. 
<FORM NAME='FOO' ACTION='/cgi-bin/fetch.cgi' METHOD='post'>

Use a javascript function to submit the form to your fetch.cgi.
In your cgi parse the form, check the 'SecretSessionID' against the one in your database, and then fetch the 'place2go'.
If i were you, upon login, i would dynamically generate the SecretSessionID which would a mix of the ip/time/email and would expire after 1 hour. 
function fetch(astring)
{
  document.forms.foo.place2go.value=astring;
  document.forms.foo.submit();
}
For links use "<a href='javascript:fetch('filename.html');'>foo2</a>
