In another strange twist, we've hacked a solution to this. adding a bogus
session cookie now seems to solve this problem. We can post more that 2K at
a time:

%> curl -b "MySession=ASFDLKJASDF92O2I3JF09SUDF09SXXJLSF" -v -d
"clearing+test+3=xxx[lots and lots of x's]" --url
"http://testserver/TestServlet"

If you change the name of the session, it bombs again. Really weird. It
seems like some sort of strange interaction between libcurl and weblogic's
session tracking.

any ideas?
