I have a machine runing T3.6 with Webstar 1.32 on Mac OS 7.6.1 which ran an
Aldi Superstores site created in Tango for over 2 years (until they
recently centralised all their web in Germany). Each week 14 new images
ranging in size up to 50k were loaded up via a Tango file upload mechanism
which worked very reliably...
Except when my clients started using IE on the Mac on an ADSL connection
which proxied everything. I found that the pages coming from the server
were being cached and eveytime they tried to upload they would suffer
similar results as what you are experiencing. Eventually, because I didn't
want to recode the app to create new pages with entirely new URLS each time
accessed, I simply told them to use Netscape and turn off page caching -
they never had this problem again.
I did have a problem with the Tango server right in the beginning, but I
solved that by increasing Webstar's (i am using the Tango plugin) app
memory. A incresae of emeory size and a restart of the server and
everything worked fine from then on.
On my server it is set to a fairly short variable timeout of a couple of
minutes, but the buffer size has been left at 64k I'm pretty sure - I'll
check it.
