I'm currently using zope 2.3.3, apache 1.3.20, and fastcgi. So far it works quite well. However, I'm trying to support large transfers, protected via a acl_user (passwords, expiration, etc.). Each download/transfer could be 20-50mb. Initial implementation is done by setting the response header to be an binary attachment, then use the RESPONSE.write() command to stream out the data. However, it appears FCGIServer buffers the *entire* 20mb before sending it out to the apache mod_fastcgi. This won't work for me, as it's a huge memory hog, plus there's a noticeable delay before the buffer is flushed out to apache. The FCGIChannel sendDataRecord() and push() shows that buffering is turned on, due to some thread related issue. Forcing it off indeed shows problems when there are multiple connections If I didn't have to deal with passwords/expirations, I could have done this outside of zope. Is there a better way to handle this? How does www.zope.org deal with this? Thanks, Albert Ting (alt@sonic.net)
