same-origin

Checks if two URLs pass the "same origin"-policy (RFC 6454)

Installation

Run npm install --save same-origin to include it in your project.

Works well with browserify.

Usage

var sameOrigin = require('same-origin');
var url1 = 'http://example.com/some/page.html';
var url2 = 'http://example.com/some/other/page.html';
var url3 = 'http://espen.codes/nodejs';
sameOrigin(url1, url2); // true
sameOrigin(url1, url3); // false

same-origin works in most environments:

// CommonJS
var sameOrigin = require('same-origin');

// AMD (Require.JS, yepnope, dojo...)
define(['same-origin'], function(sameOrigin) {
    // ...
});

// Browser global (if CommonJS/AMD environment not found)
window.sameOrigin(url1, url2);
