Hi,

So in your case, the client and server are the same computer? Or else, the files in question are NFS mounted on both?

The first case true.

Otherwise, there's no way the external method on the *server* could directly manipulate the file on the *client*! (That really would be a security violation -- and I can tell you the web doesn't work like that! :-D).

Yeah I found that a out little late. I just wish I could find some time to read Zope Devlopers guide, I ve been dying to do that for some time now.

If that's what it did before, then, yeah, I think you're going to be doing some rewriting. It shouldn't be hard, though -- you just eliminate the "f = open(filename, 'r')" with something that directly assigns the file I/O object. The whole point of file I/O objects (StringIO and presumeably HTTPFileUpload) is that they act just like files.

I was also planning to do something similar. Hope I won't be breaking it again. Thanks Shashank
