Hi, I need to write a little JS file (to place in not rails web site)  
in which I need to make an ajax call  
like this http\_request.open(‘GET’, url, true); where URL is a rails  
url of my web site ([http://my-site.com:3000/controller/action/par1/](http://my-site.com:3000/controller/action/par1/)  
par2) and return a string in the web site that start the request and  
put in a dedicated DIV.  
The JS should be added to any web-site.

Yo can’t write an ajax request for a different website.  
For example, if you are on [www.example.com](http://www.example.com) you can’t make a request to  
[www.google.com](http://www.google.com).  
There are other solutions if this is the problem

You cannot. The browser will not allow it.

What you’re describing is functionality along the lines of a widget.  
There’s a few ways to do it, but the easiest for the remote site is  
usually an iframe.

Investigate how widgets work, an you’ll get some ideas.
