Its simple: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http:// www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title></title>
<script src="jquery.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $.get("http://twitter.com/statuses/user_timeline/ 19092829.rss"); }); </script> </head> <body> </body> </html> In IE and Opera this works perfectly, but in FF 3.5, Chrome, and Safari I get a 400 Bad Request. Looking at the request using Fiddler2 and FireBug, something is replacing GET with OPTIONS. But in IE and Opera, it is still showing up as GET. I dont get it????
