Use jQuery.ajax (or it's wrapper functions such as jQuery.getJSON) to
cover all cross-browser issues.
And as indirectly suggested above. JSONP is the solution for cross-
domain scripting.
What it means is that that source (in this case toolserver) has a URL
parameter (say &callback=), the script then returns the folllowing:
callback({ my: 'data' });
This is the exception / work-around to same origin policiy as it can
be done through a simple script tag because there is a callback.
This callback function can be dynamic and generated on the fly with
jQuery by using a ? as callback
Example:
http://toolserver.org/~krinkle/tmp/jsonp_example.php?callback=myFunc
jQuery.getJSON( 'http://toolserver.org/~krinkle/tmp/jsonp_example.php?callback=
?', function(data){
alert(data.hello); }
);

Hi all!
what's the best way to get around the same original policy to fetch
data from
the toolserver with a XMLHTTPRequest in a Wikipedia gadget? Is there
a best
practice, a nice and easy, generally usable method? what would it
take to make one?
I know that some gadgets have been doing this, but I also know that
it's a bit
tricky. I think a general solution to this, documented somewhere,
would make
life a lot easier... does something like this exist? if not, why not?

PS: while i'm at it, is there a wrapper function for XMLHTTPRequest
in the
standard MEdiaWiki JS? I don't want to re-invent a sucky wheel :)
