I have website that use XMLHttpRequest (jQuery, actually). I also have another site running on the same server, which serves a script file that makes XHR requests back to THAT site, ie. http://mysite:50000/index.html includes <script src="http://mysite:9000/otherscript.js"></script> and http://mysite:9000/otherscript.js incl...
Hi folks, I got the following Request Queue implementation from this blog: http://dsgdev.wordpress.com/2006/10/28/building-a-javascript-http-request-queue/ and want to wrap it with a object variable. Unfortunately the variable initialization inside doesn't work. Hope someone can help me with this stuff. Thanks in advance var reque...
I have a situation where my website needs to quickly retrieve data from my server via AJAX. My website runs on port 80, serving normal web pages. I normally run my AJAX server on port 8001 (I use JSONP and this works fine). This works for most users. However, some users are blocked from high ports by their local firewalls. In order to ...
I'm doing an AJAX download that is being redirected. I'd like to know the final target URL the request was redirected to. I'm using jQuery, but also have access to the underlying XMLHttpRequest. Does anyone know a way to get the final URL? It seems like I'll need to have the final target insert its URL into a known location in the he...
Hi there, I have a report in our internal system that can return anywhere from 1 days data to a full years. Because of this, the report can take 0.5 seconds or over 45 seconds to generate everything. The report lets you modify a bunch of filters, all which when modified, fire off an ajax request very simply: var ax = $.ajax({ type...
I'm having some problems with a jQuery control we made. Suppose you have a dropdownlist that allows you to enter the ID of the item you're looking for, and when you press ENTER or lose focus in a textbox it validates via jQuery that the ID you entered is correct, showing an alert if it doesn't. The thing is that when an ordinary user en...

When requesting data with: <param value="data-file=http://url-to-my/json.script" name="flashvars"> via an SWF file, what request type would "http://url-to-my/json.script" receive. It doesn't seem to be a "xmlhttprequest". Is it the same as a request from a browser? ...
I was just reading how FaceBook designed their chat system, and it reads: "and having that iframe's JavaScript make an HTTP GET request over a persistent connection that doesn't return until the server has data for the client. The request gets reestablished if it's interrupted or times out. This isn't by any means a new technique: it's a...
I'm developing a greasemonkey plugin, which is supposed to send a form in background using POST (GM_xmlhttpRequest) on an application not under my control. That application is written in PHP and seems to expect all its input in windows-1250 encoding. What I need to do is to take all the form fields as they are, edit just one of them and ...

My userscript's task is fairly simple -to listen to XHR requests via an XHR bridge sort of functionality, manipulate the data received, and return it back. Everything happening transparently, of course. I came across this reply (http://stackoverflow.com/questions/629671/how-can-i-intercept-xmlhttprequests-from-a-greasemonkey-script/6297...
Hi, I didn't write the following code and I am not a Javascript expert. So please excuse me if it seems to you a trivial bug. However here is the code: jQuery.ajax({ type: barobj.method, url: handler, beforeSend: function (request) { request.vote_id = vid; ... }, complete: function (request, textSt...
In IE using Javascript, is there way to know if doing a regular GET on a URL using XmlHttpRequest will pull its data from the cache or hit the server? If there is no way to know in advance, is there a way to tell XmlHttpRequest to NOT hit the server, and instead pull from the cache if possible? To clarify: I understand how browser cach...
I'm trying to download an HTML page, and parse it using XMLHttpRequest(on the most recent Safari browser). Unfortunately, I can't get it to work! var url = "http://google.com"; xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", url); xmlhttp.onreadystatechange = function(){ if(xmlhttp.readyState==4){ response = xmlhttp.responseTe...
I've got a web page that uses XMLHttpRequest to download a binary resource. Because it's binary I'm trying to use xhr.responseBody to access the bytes. I've seen a few posts suggesting that it's impossible to access the bytes directly from Javascript. This sounds crazy to me. Weirdly, xhr.responseBody is accessible from VBScript, so...

But as frequently we move mouse to other tabular contents previous Ajax responses are being displayed inside popu...
