Regarding XSP page caching, you need to define couple of methods. Read on about caching of XSP in the thread: http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=100142724706511&w=2 (This theme were discussed at least couple of times on user list) Vadim > -----Original Message----- > From: Eisert, Wolfram [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, December 12, 2001 10:37 AM > To: '[EMAIL PROTECTED]' > Subject: [PATCH] AW: XSP page getting called TWICE!
