Hi Siegfried, thanks for your reply.
The Problem is that my VTL runs in the Context of the Intrexx Portal Framework. I can only place a VTL Part inside of a HTML-Page generated by Intrexx, therefore I don't have any possibility to generate or modify any Headers of the page (actually I only get a <div> </div> where the result of the VTL is embedded. My usual problem with storing the document on disk is the possible (though with VTL and in my environment quite unlikely) flaw of this (any kind of exploit could (!) gain access to another part of the disk. And it's quite unelegant ;-) Cheers, DD ______________________________________ Dirk Dörflinger IT Operator Telefon +49 (0) 7627 9239 - 230 Telefax +49 (0) 7627 9239 - 100 H2O GmbH process water engineering Wiesenstrasse 32 79585 Steinen/ Germany www.h2o-gmbh.com ______________________________________ Clevere Ideen für sauberes Wasser! ______________________________________ > -----Ursprüngliche Nachricht----- > Von: [EMAIL PROTECTED] [mailto:itext-questions- > [EMAIL PROTECTED] Im Auftrag von Siegfried Goeschl > Gesendet: Donnerstag, 22.
