Nice code. But its raising to me: callback is not defined. I'm using OX.AJAST.call(url, 'callback', f1, 1000, false); and my url give me callback('data'); I need some help. Thanks, Ronaldo.</p> Hi.

Is it possible to change the request headers before the call? I'd like to prevent caching. I was thinking to use cache-control no-cache as request header. Please help me how to inject that.</p> <p>thanks, --IStvan</p> Great little code. Is it possible to change the request headers before the call? I’d like to prevent caching.

I suspect your issue is something else. Javascript always runs in a single thread (although the XHRs themselves are run asynchronously), so synchronization is not an issue.</p> Ali: This is weird.

however there is a bug I would like to mention

In my application I need to send like 4 to 5 requests “one after the other (onload) ” to different servlets in a “XYZ” server. and since your callbackid variable is static , this will cause some unstable response and incorrect data!

anyway :D … I just changed this line: var callbackid = ‘callback’ + OX.AJAST.callid;

to:

var callbackid = ‘callback’ +Math.floor(Math.random()*9999999)+ OX.AJAST.callid;

thanks for this great lib :D

This library is great. however, I did manage to fix two things (1 is included above in the comments as well, but not fixed on the file linked from the article).

Line 108: OX.AJAST.Broker.callid++) should be OX.AJAST.callid++

Line 123: replace the line with the following: if (this.url.indexOf(‘?’, 0) > -1) this.url += ‘&’ + args.join(‘&’); else this.url += ‘?’ + args.join(‘&’); OX.AJAST.call(this.url, this.cb, callback, this.timeout, this.jsonmode);

Thanks for your help. I am indeed running into the second injected tag issue with Firefox and was wondering how I can add a timeout and where to accomplish this in the certain cases I want to make back to back calls.

Thanks again, great stuff here.
