RESTful – phrase book

agile – …

coupling – less coupling between client and server, so server side changes are easier. I think SOAP requires client rebuild.

b2b – still dominated by SOAP

resource-oriented services – …

object – each URL logically represents an object, which you can Get (query), POST (create), PUT (update its content) or DELETE

Q: is REST simpler than traditional SOA or SOAP web services?

Q: the concept of “resource” — does it sometimes mean a database record?

idle timer inside app server engines

I just realized idle timers are often “passive”. You may imagine a separate thread performing periodic polling to detect idlers[1]. Well, not common.

Idle Timer is just a “state” added to the “decoratee”. When the decoratee becomes idle, that time is saved in that state field. When a “Request” is received from a client Call from any thread, the state is checked. If idle time has been too long, we kill that decoratee or mark it as obsolete

See P189 [[Weblogic]]

[1] Heart beat checker is that way.
