multiple xhr requests

[Erich Lin]

Hi I have a window that looks like this

--------------------
| | Enter
--------------------

That box will take a command that the user enters and runs it on a
server in the background loading a new window for the user to view the
results. Is there a way to take multiple xhr requests so that the next
request the user enters , a new window will pop up right away, instead
of stalling for the first xhr request to finish?

thanks

also, i would like some of the commands to go on the same page so not
all of them will be on new windows

Dear Lin,

your question is not very clear.

What you want is :
* Build an application, probably in rails (you should have asked on
that list btw).
* Use XmlHttpRequest (the xhr you mention) to submit some complex
operation.
* Operations should be non-blocking and return a value to the emitter.

What you need in your page, is two XHR. One that submits calculations,
and the second that periodically gets the results.

In your controller, you need two methods. "submit" and "response" for
example. Submit launches a new Thread in which it does the
calculations. Once finished, it fills the user's session for example,
or stores it in a class variable. Response looks in the sessions for
the results. Now I'll let you the pleasure of the implementation

Cheers,

By multiple, I meant like the user clicks "enter", and then the user
types something else and clicks "enter". I would like thsoe XHR
requests to be handled simultaneously

thanks
