Greetings all.

I have been utilizing libcurl via javacurl for quite a while now with good
success. Recently, my script is having some problems because of receiving a
"302 Object Moved" http status. Basically, my script hits a URL, logs in to
a secure site via a digital certificate, performs some various operations,
then submits data via a get. After submitting the data, I receive the 302
status. By looking through the output, there is an indication that I must
"issue another request" to the login url.

The code below is called after successfully logging in and parsing some
values from various places on the site. The java code mirrors pretty much
exactly what would be implemented via libcurl:
cg.setopt(CURL.OPT_URL,"the url" );
cg.setopt(CURL.OPT_VERBOSE, 1);
cg.setopt(CURL.OPT_HTTPGET, 1);
cg.setopt(CURL.OPT_FOLLOWLOCATION,1);
cg.setopt(CURL.OPT_ENCODING,"gzip, deflate");
cg.setopt(CURL.OPT_USERAGENT,"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT
5.1; SV1; .NET CLR 1.1.4322; InfoPath.1)");

My output is below with the internal stuff marked out:

Thanks in advance for any feedback. I *hope* I did not do something
ridiculous....although I will not be surprised if that is the case :)
