Re: [Simpleweb-Support] Tutorial example out of date?

[Toby <tob...@gm...>]

Great thanks.

I was looking at AsyncWeb which talks about "asynchronous throughout" and was interested in the difference (having not really understood AsyncWebs description). The (Simple) asynchronous stuff were discussing is the thread per request model I guess and we can avoid running out using the queue (as in the example) so I was curious about an alternative that AsyncWeb tries to describe...

...bit random I know, but if you have any comments I'd be interested :)

Cheers

Toby

For instance if your service needs to do something that requires some time to complete, for example waiting for a JMS message, then asynchronous behaviour here becomes a real advantage. As it allow many connections to be open servicing requests without then need for a separate thread for each.

Is it the simple case blocking? Clients will wait for a request to complete and in the mean time, the server won't accept new connections?
