We've been using libcurl 7.8 and 7.7.3 to post data to a servlet running on
Weblogic 5.1 sp 9. For some strange reason, if we go ONE byte over 2047, we
get an exception thrown in our server, way before our own code, in the
depths of weblogic. It's made even stranger by the fact that we can easily
post more the 500K to the servlet using a web page form (pasted into
textarea), using the Java net api, or a COM api. We also did a test install
of resin, another servlet engine, and it accepted libcurl posts just fine.

This behavior is also present in the curl command line tool.

Using SSL or not doesn't seem to matter.

Here's the curl command we use to test data:

%> curl -N -v -d "test+3=xxx[2000 more x's cut for brevity]" --url
"http://testserver/TestServlet
