yes, but you don't get the HTTP headers (in a zope application) until
after the file upload is completed. If you use Apache's
LimitRequestBody directive you can limit file sizes uploaded by a user,
but if the user exceeds this limit they get an apache error response (as

from infrae. It deals with uploading large files via apache.
They say something like:
to handle upload:

I had a quick look at tramline, an interesting apache add-on, but it still
uploads the entire file before asking the application server whether it

application can access it). If the file is not accepted it is deleted from
the upload directory.
