Heartbeat notes [feel free to ignore]

[David Pollak]

Folks,

I'm rooting around in Lift/Jetty code to try to create a heartbeat system.  I'm going to post random notes as I learn things... kinda stream of consciousness.

We're not the only ones that care:

It's likely that there are a ton of factors (keep-alive, proxy, etc.) but perhaps an approximation will do.

More as I find it.

Thanks,

David

Okay... I've done this checkin:

http://github.com/dpp/liftweb/commit/be575ea2ceb6510c17b905e12b2d9b22db892d37

It adds a heartbeat function to LiftRules for Comet-enabled containers (read Jetty).  There's a modification to the examples code to demonstrate it.

On my local box, "it worked fine".

Looking for feedback on (1) if it gets the job done for Daniel & Co. and (2) how we can make it more general so that we can bring it forward to Lift 2.0.
