Question

I want to extract a page by javascript (client based language) the problem is the third-part remote url doesnt not allow ajax request when i do this req without the header X-REQUESTED-WITH it gives the expected data with 200 Success in response but when i req it with that header it give 403 Forbidden with no content in respone .

i want to know how to req a page without the header X-REQUESTED-WITH in javascript , ajax , jquery or any client based language .

Please help me .
thanks

Answer 1

The X-REQUESTED-WITH header is not “standard”. jQuery for instance will add it manually.

So by doing a default XHR request

var xhr = new XMLHttpRequest();

xhr.onreadystatechange = function() {
    if( xhr.readyState === 4 ) {
        console.log('done');
    }
};

xhr.open('GET', 'hello=50', true);
xhr.setRequestHeader('FOO', 'BAR');
xhr.send(null);

there will not be this header. In the above simplified example we added a custom FOO request header instead, that is the same thing like jQuery adds the X-REQUESTED-WITH header into its ajax requests.
