When OpenNMS monitors a HTTP service it does not accept and send cookies. Many web applications use cookies to track sessions and OpenNMS creates a new session for each poll.
Extend HttpMonitor to have an option to enable cookies

I believe that the PageSequenceMonitor will store and transmit cookies. It should satisfy any use cases involving logging into a form-based authentication page for instance. Please upgrade to the latest version and you should be able to carry out this type of polling. Marking as fixed.
