In JS is it possible to fetch the content of a web page assigning it to a variable? For example, why the following toy code does not work?
var req = new XMLHttp
If you really need to do this, you can try using jQuery and iFrames (read more at (read more http://softwareas.com/cross-domain-communication-with-iframes).
Also, you can try with Access-Control-Allow-Origin: http://yourdomain:1234/ in headers, google for Cross-Origin Resource Sharing. It's relativelly new though, not all browsers know about this. That also depends if you have the control of the other server headers generation and few other things.
