user-agent

I'm using JQuery to issue a AJAX-Request to my own Webservice. I need to set or modify the User-Agent HTTP-Header for the HTTP-AJAX-Request, how can I do this the easiest way? I tried the hint provided by some users to use the setRequestHeader Method to set the User-Agent, but this does not work. It does in fact work for other newly created headers (like X-Test-Header ) but it does not work for User-Agent . Thanks!

I want to offer the right version of a download. The versions I have are: 32-bit Windows 64-bit Windows Linux Detecting Linux using the User Agent field is easy; but is it possible to reliably figure out if Windows is 32-bit or 64-bit?

Immediately, I've slammed into one of the walls of using an actual browser for javascript testing. Specifically, I need to change navigator.userAgent to simulate a few hundred userAgent strings to ensure proper detection and coverage on a given function. navigator.userAgent is readonly, so I seem stuck! How can I mock navigator.userAgent? User Agent Switcher (plugin) can switch FF's useragent, but can

I am using jquery to build a request to the Twitter Search API. I am using jsonp, as is needed for cross-domain requests. However, the Twitter API specifies that you should set a unique User-Agent for these requests, and limits your requests if you do not. The problem is, I see no way of setting this header via jquery. This is the code I am using: $.ajax({ url: 'http://search.twitter.com/search.json', dataType: 'jsonp', type: 'get', data: { q: 'twitter' }, success: function(data) { alert(data.results); } }); I have tried using the beforeSend method, but it appears that this event is not firing
