I have done a bit of testing on this myself (During the server side processing of a DWR Framework Ajax request handler to be exact) and it seems you CAN successfully manipulate cookies, but this goes against much that I have read on Ajax best practices and how browsers interpret the response from an XmlHttpRequest. Note I have tested on...
I want to upload and then process a file in a Ruby on Rails app. The file upload is usually quite short, but the server-side processing can take some time (more than 20 seconds) so I want to give the user some indicator - something better than a meaningless 'processing...' screen. I'm trying to use the following code in the view <%= p...
Is there a documented max to the length of the string data you can use in the send method of an XMLHttpRequest for the major browser implementations? I am running into an issue with a JavaScript XMLHttpRequest Post failing in FireFox 3 when the data is over approx 3k. I was assuming the Post would behave the same as a conventional Form ...
I'm using the following in the web page but can't get a response from the server while it's processing <script type="text/javascript"> <!-- function updateProgress() { //alert('Hello'); new Ajax.Request('/fmfiles/progress_monitor', { parameters: 'authenticity_token=' + encodeURIComponent(AUTH_TOKEN), onS...
We are designing a web application using ASP.NET and AJAX and we want to host our WCF Service Layer on a different website and make JavaScript calls to the Service Layer from our client pages. We understand that the browser will not allow AJAX calls to a different port or domain. What is the best way to architect a solution? We are co...
I want to use XMLHttpRequest in JavaScript to POST a form that includes a file type input element so that I can avoid page refresh and get useful XML back. I can submit the form without page refresh, using JavaScript to set the target attribute on the form to an iframe for MSIE or an object for Mozilla, but this has two problems. The mi...
http://developer.yahoo.com/javascript/howto-proxy.html Are there disadvantages to this technique? The advantage is obvious, that you can use a proxy to get XML or JavaScript on another domain with XMLHttpRequest without running into same-origin restrictions. However, I do not hear about disadvantages over other methods -- are there, and...
Is there anything in the header of an HTTP request that would allow me to differentiate between an AJAX call and a direct browser request from a given client? Are the user agent strings usually the same regardless? ...

I have a DTS job that is using the MSXML2.XMLHTTP3.0 object to generate a post request to an ASP.NET application. Under the covers, the ASP.NET application is using System.Reflection to acquire some assembly information and I receive the following exception: System.Web.HttpException Error Code: -2147467259 Message Session state ca...

I am trying to update an old JavaScript function used to detect support for AJAX (i.e. the XmlHttpRequest object). I've looked online (including SO) and found various solutions but I'm not sure which is the most efficient for simply detecting support. The current function is: function IsSyncAJAXSupported() { var isSyncAJAXSuppor...
Is there a way to use XMLHttpRequest in combination with other domains? I would like to parse some xml from Google without having to use a server so it is minimalistically complex to run. var req = getXmlHttpRequestObject(); ... req.open('GET', 'http://www.google.de/ig/api?weather=Braunschweig', true); req.setRequestHeader("Con...
Is it possible to do a HTTP Head request solely using an XMLHTTPRequest in JavaScript? My motivation is to conserve bandwidth. If not, is it possible to fake it? ...
Am I correct to understand that the abort() method for XMLHttpRequest objects is only available starting from MSIE 7? If so, what equivalent option do I have for aborting an XMLHttpRequest object on timeout in MSIE 6? Using a JS framework to abstract the problem away is not an option at this time I'm afraid :(. I'm on a legacy system th...

I am using jQuert .ajax function to call a page method. The site is using FormsAuthentication. So when an authentication ticket expires a call to the page method will obviously cause a redirect to the login page. Now, the geniuses that wrote the System.Web.Handlers.ScriptModule decided that if for some reason a REST style call to a pag...
