It's not high on my list of issues, but I can see your use case. Putting files in the right place to start with seems infeasible, but being able to move them around later seems reasonable (and controlling what directory they are written to, so you can keep them on the same device). I'd accept a patch, probably to WebOb. Somewhat relatedly, someone recently did a rewrite of cgi, that might be worth thinking about: http://mail.python.org/pipermail/web-sig/2008-September/003587.html -- Ian Bicking : [EMAIL PROTECTED] : http://blog.ianbicking.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
