load content from external page into another page using ajax/query

May be I just don't get something.

I want to get html page from other site, let it be http://www.server.com/somepage/param

In my js code:

  var url = "http://www.server.com/somepage/param";
   $.get(url, callback);

Chrome says "Failed to load resource".

What is wrong?

You're running into restrictions imposed by the Same Origin Policy. In short, AJAX calls to a different domain are prohibited and will always fail.

You need to either use JSONP (mostly applicable to data returned by APIs) or proxy the request through your own server/domain.

Well, but I've got a chrome extension, and it makes such requests, and get the information from site I need. How? I looked at js source it uses jQuery.
It uses special permissions given to Plugins. Here's an excellent writeup about how to implement this: sarajchipps.com/2011/01/…
Oh, thank you very much for your answer. Sadly that, this simple solution works only in crhome, It seems that I need to find a way to use proxy solution with my ROR 3.1 server
But what about this document: w3.org/TR/cors (infromation from here merbist.com/2011/09/14/how-to-cross-domain-ajax-in-a-ruby-app - However, most browsers (IE 8+, Firefox 3.5+, Safari 4+, Chrome) implement a simple way to allow cross domain requests as defined in this w3C document.)
Well, can you get the remote host to send a Access-Control-Allow-Origin: http://yourhost.com header?

The simple answer is, no, this is not possible. Cross Domain AJAX is not allowed. However, you can find a (working) workaround here:
