I am using Apache 1.3.6 and JRun 2.3.1 on both Win98 and Linux Redhat
5.2/6.0, but my JDK is still 1.1.7. I don't have this problem (yet?), and I
have uploaded files that that are 345Kb to far.
But, I've only been running on a LAN, yet I noted that the file upload takes
longer than it should. That is, if I ftped that file, it would transfer in
a 1 second, but via the POST it seems to take the browser 56 seconds! Even
assuming some horrible encoding scheme used to HTTP POST I can't believe it
would be 56 times bigger.
I wonder if there is any problem with the duration of the uploads, that some
servers are terminating connections that stay open "too long," since one of
HTTPs saving graces over the rather unreliable Internet (especially for
dialup users) is that TCP connections are generally short-lived.
