Hi! Another way to solve the spider problem is to simply reject any non-std pages to spider User-Agents. So please put the UserAgents of your favourite spiders on http://twistedmatrix.com/users/jh.twistd/moin/moin.cgi/WebSpiders so I can set up a default config list for them. To get at the U-A fields, simply check your event log. Ciao, Jürgen
