$.getJSON() with url '/' doesn't work in IE

[jbruler@…]

$.getJSON('/', function(){alert('ok');})

This code doesn't work in IE (version 8, 9). It doesn't send any request to server. In other browsers (firefox, opera, chrome) it work properly. I test it with jQuery 1.4.2 and 1.6.2 with same result.

Little mistake, code looks like this:

$.getJSON('/', data, function(){alert('ok');})

Confirmed: ​http://jsfiddle.net/GEJwe/ (and there's a workaround in there using

$.getJSON('//', function(){alert('ok');})

however, I need to discuss with the rest of the group as to whether this is simply expected (but undocumented) behaviour.

Further investigation: ​http://jsfiddle.net/Ga9sB/. So this works fine with ​cache:false using the complete $.ajax call but not with getJSON. dmethvin and I are investigating.

Now that's weird. You guys found something more or do you want me to hop in and see how we can fix this for 1.7?

@jaubourg if you can hop in and see if this is still an issue that would be great.

In IE8 and IE9 I can see the browser making the request. It doesn't alert because the response isn't a valid JSON response (at least for me). As the docs say, a bad response often/usually fails silently.
