I used Ethereal to capture the client/server conversation; is that what you
were getting at? I've attached the logs to this message. With the disclaimer
that I'm way out of my depth on this, a few observations:
1) I'm not sure why the HTTP/1.1 100 Continue is unexpected, but that
message is coming from HttpClient in any event. I see a bit of discussion of
this issue over at the Commons mailing list; there might be some options
that Slide could set to quiet it.
2) Now that I've captured the connection, I can see that the IIS server logs
lie: it's not really a 403 Forbidden, but a 403.9 Too Many Users. IIS /does/
have a maximum number of connected users, but I'm not sure off the top of my
head what that might be. In any event, I'm doing my uploading sequentially,
not simultaneously, so there should never be more than one user connected at
a time, AFAIK. Is Slide failing to release its connections when it finishes?
This same log is also when the SocketException throws; maybe HttpClient
doesn't understand or expect Connection: close?
