Hi,

I quote an old Tim's answer about HTTP and polling.

We have a problem with this HTTP polling and asynchronous messaging. One second
is too frequent and we have bandwith cosntraints. Is it planned to make the poll
interval configurable? Is it possible (and planned) to replace the HTTP polling
by pushing?

Regards.

The only way to change the poll interval at the moment is to modify the

connect() method in org.exolab.jms.net.http.HTTPInputStream class and
extend the sleep() to something larger

than 1000.

The only other planned enhancements to the http connector is to provide
support for blocking reads. This ties

up a thread in the http server so there are tradeoffs using each
approach.
