Bug #5781 --> more connection cache fixes. ProcessCurrentUrl wasn't set up to run multiple urls as it was setting the connection status to -1 whenever it finished. This was causing the next call to process current url to fall out. I also re-organized SetupUrl to make sure m_runningUrl gets properly initialized on multiple calls to LoadUrl.
