once upon a time in a browser
refferer puzzle

why does this work in Firefox but not in IE?

<script language="JavaScript" type="text/javascript">

if (document.referrer == "http://mysite.com/group.html")
document.write('You came from group');

Some things don't work quite right in browsers when working within file system (ie file: protocol). It took me a while to find this out for the onerror event for images in Moz.

If you have a local webserver, try getting the document.referrer property, and it will magically appear.

Put the script inside a page being served from a webserver and it will work in IE too.

I've decided to go with php, at least one thing that actually works in this world lol

Don't forget that the referrer string can not be trusted. A user can alter what, if any, data they send as the referrer.
