I would add 4) the front-end server can provide "sanitizing" of requests from buggy or malicious clients. A search of the mail archives will find many people advising the same thing. I recently experienced it myself. I wasted a lot of time recently trying to find out why Zope was leaking memory on XML-RPC requests *only* from a certain client. The leak was small, but under load, Zope would exhaust the system's memory after a few days. I could never determine the cause, nor could I provoke the leak with other clients. Then one day, the client switched from one Java XML-RPC library (an old version of the Apache xmlrpc library) to another (Redstone I think), and immediately the symptom stopped. Zope's memory usage became quite stable. Nothing else was changed. A good, battle-tested reverse proxy in front of Zope should help protect against that kind of thing. -- Paul Winkler http://www.slinkp.com _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
