Apologies if I sent two of these -- having connectivity issues.  It's also
late and my first response bordered on boneheaded.

Are you connecting to http://localhost:9000?

I also think you're overcomplicating things a bit.  If it were me, I'd use:

ssh -L1810:appserver:1810 

Then browse to:

http://localhost:1810
