Javascript Ajax (More)

How do you link to an Ajax page?

(or indeed to any Javascript-modified page, Ajax or not)

Security - Same origin policy

Elsewhere - JSONP as workaround to same-origin policy

Security - CSRF

CORS - Cross-origin Ajax


CORS proxies

Even if the server does not cooperate, you can use a CORS proxy like corsproxy.io to fetch arbitrary resources off the Internet:

var url  = ...   // some resource on a normal website  

var curl = "https://corsproxy.io/?" + encodeURIComponent ( url );   // CORS-enabled URL 

$.get ( curl, function ( data ) 
  // we have got the data
