There can be many non-bug reasons that the browser may fetch a script. The server may be returning a don't-cache header for example. Can you post a complete example?

up up. opera v10.63 win

my code:

var s = document.createElement("script");
s.setAttribute("src","sample.js");
s.setAttribute("type","text/javascript");
$('head').append(s);

i found solution. remove next code (line: 5663-5672 in jquery-1.4.3.js)

// Set header so the called script knows that it's an XMLHttpRequest
// Only send the header if it's not a remote XHR
if ( !remote ) {
xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
}

// Set the Accepts header for the server, depending on the dataType
xhr.setRequestHeader("Accept", s.dataType && s.accepts[ s.dataType ] ?
				s.accepts[ s.dataType ] + ", */*; q=0.01" :
				s.accepts._default );
