Python CGI - Presenting a zip file to user

Hi all,

I'm working on a cgi script that zips up files and presents the zip
file to the user for download. It works fine except for the fact that
I have to overwrite the file using the same filename because I'm
unable to delete it after it's downloaded. The reason for this is
because after sending "Location: urlofzipfile" the script stops
processing and I can't call a file operation to delete the file. Thus
I constantly have a tmp.zip file which contains the previously
requested files.

Can anyone think of a way around this? Is there a better way to create
the zip file and present it for download "on-the-fly" than editing the
Location header? I thought about using Content-Type, but was unable to
think of a way to stream the file out.

Any help is appreciated, much thanks!

Thanks! That worked like an absolute charm.

Just a question though. I'm curious as to why you have to use the
msvcrt bit on Windows. If I were to port my app to *NIX, would I need
to do anything similar?

- James
not needed for *NIX as *NIX does not have a notion of binary- vs text-

I seem to recall not needing the msvcrt stuff a while ago on Windows
but recently needed it again for Python CGI on IIS

How does Ruby compare to Python?? How good is DESIGN of Ruby compared to Python? Python's design is godly. I'm wondering if Ruby's is godly too.

Hi, I want to write a small system that is transaction based. I want to split the GUI front end data entry away from the file handling and record keeping. Now it seems almost trivially easy using the sockets module to communicate between machines on the same LAN, so that I want to do the record keeping on one machine.
