interfering with Ajax.Responders

Hi,

Is there a way to get a handle to the ajax-request that gets caught by
a responder?
At the moment I use this:

  load: function(url) {
    if(Ajax.activeRequestCount < 2) {
      new Ajax.Request(
        ''/people'', {
          method:''get'',
          onSuccess: this.parseAjaxResponse.bind(this)
      });
    } else {
      this.load.bind(this).defer(url);
    }
  },

to make sure there aren''t too many connections open. IE sometimes
tripped on those.

I would like to put this functionality into a responder so I don''t
have to do it everyplace i create requests.
It would be nice if the onCreate responder was able to pause the
creation, and resume when ready (just like above).

Any possible solutions?

thanks
Mathijs

Re: interfering with Ajax.Responders

If you just want to count connections, current versions of Prototype  
already do that for you, via a built-in Ajax responder.

Take a look at "Ajax.activeRequestCount".

Re: interfering with Ajax.Responders

As you can see in my post, I use this method already.
I don''t just want to count connections, I want to defer connections
until others are finished.
I found a way to do this, but for that I need to implement it at every
spot where I use Ajax.Request.
So I''m looking for a way to overload the default behavior of
Ajax.Request or modify it using a responder.

tnx anyway

Re: interfering with Ajax.Responders

Im not sure if this is what you''re looking for but I have developed a
method of queuing requests such that it would only ever allow for one
XHR to be in the wind at any given time.

Re: interfering with Ajax.Responders

It looks very usable indeed.
I''ll try it out tomorrow.

How should I use this instead of new Ajax.Request() ?
