<br>
In 3.3, you have triggers, in your context I'd suggest you look at
the
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
EP_TRIGGER_DOC_URL_REWRITE trigger called by Apache::Rewrite.<br>
<br>
Look this up for inspiration:

Give us a shout if you ran into problems.<br>

non-public documents.<o:p></o:p></p>

documents, and the generated thumbnails now inherit a security

<p class="MsoNormal">By default, when a request for a thumbnail

document, not the thumbnail document.<o:p></o:p></p>
