cache is not being false by default with datatype === "script"

[nsabena]

In jQuery 1.3.2, there was this test:

if ( s.dataType === "script" && s.cache == null ) {

s.cache = false;

}

which correctly set the s.cache value to false if s.cache was null OR undefined. In jQuery 1.4.2 this was changed to:

if ( s.dataType === "script" && s.cache === null ) {

s.cache = false;

}

(using exact equality) which no longer works when s.cache is undefined (most of the times). I think it should be reverted to the "==" comparer (s.cache == null).

In jQuery 1.4.2, as you mentioned, caching is disabled for script loads as it was decided this would be the most appropriate default option for all browsers.

It is however quite trivial to change this behavior as you're able to set ​cache:true in the options when creating an Ajax request.

$.ajax({

url: "test.html", cache: true, success: function(html){

$("#results").append(html);

}

});

Hope that helps!
