Back Button
You want to create a real back button? It's easy using SSI. Just use the directive and tag below.
<a href="<!--#echo var="HTTP_REFERER" -->">Backup Page</a>
This comes out as shown below.
One thing to remember when using this method: you will get "(none)" as a value, meaning there is no referrer and thus no page to back up to. It's a good idea, if you want to avoid 404 errors, to include a page entitled "(none)".
