Hello, For some programs I need to know in which platform the client works. I did, until now, with the Javascript code : navigator.platform, to have the knowledge. I want to do the same under Zope, but without, if it's possible, to ask the client with Javascript. In Zope we have HTTP_USER_AGENT I've tried HTTP_UA_OS, but nothing return !! Anybody knows how to do it ? Sincerily PS -------------------------------------------------- Oreka ! Nous sommes l'internet moins cher ! Surfez 25% moins cher avec http://www.oreka.com
