XMLHttpRequest most definitely works for localhost, so a more detailed description is needed.

Can you provide a real testcase (i.e. a small page you reproduce this with and the real server-side code)?

Can you reproduce this on a clean profile?

Or is this a regression (i.e. this works if you try it in a previous release)?

The same code works in production (not localhost) but not works on localhost.

I'm using ASP.NET MVC, sample returns a string "1". On non-localhost hosting everything is ok (local area network or Internet). But on my maching asynchronous callback isn't raised. IE8 and Chrome works fine. So i desided that problem is in Minefield...

That's really not enough information to do anything with....  I assume localhost is running an HTTP server?  Does an XHR not using JQuery work for you?
