Hello all,

I apologize if this is a wrong list for the question, but the
python-crypto list doesn't seem to be working (at least I haven't
received anything from there, not even the mails I've sent). Anyway I
suppose there are people here who run the ZServerSSL with Zope.

We're having some problems downloading large files from Zope/Plone
running
on win32, through an SSL connection. Uploads seem work ok.

There's been some discussion about similar issues, but with uploads
(http://www.zope.org/Wikis/DevSite/Proposals/ZServerSSLIntegration).
The variable ac_out_buffer_size in https_server.py mentioned in that
post
is not present in the current version (or at least I haven't found it).
The ac_in_buffer_size is assigned a value of 32k (1 << 16 bit shift
operation). We've tried to change this value but with no success.

This seems to be a problem only with SSL connections. If we download the
same file (say, for example of 200MB) through HTTP connection the file
transfers correctly. The same transfer through an SSL connection
produces
a corrupted file.

M2Crypto 0.13 (suppose, The ZServerSSL has been installed with the
Windows
installer), Plone 2.0.3, Zope 2.7.0, Python 2.3.3 on win32.

Kind regards,

Tuukka
