chrome extension: refuse header "date" in ajax request

Question

I have a javascript code to be used for api (ajax) and I need to send header "date" to api-server (required header), but chrome tells me 'refused to set unsafe header "Date" ' and I get response from api-server like "missing required http date header".

I'm using jquery.

code sample:

var d = new Date();
var headers = {};
headers["Date"] = d.toUTCString();
jQuery.ajax({
            url: '<some HTTPS url>'
            type: "get",
            crossDomain: true,
            headers: headers,
            ....

})

the same code works fine in firefox. does anybody have any ideas how to fix it?

Answer 1

Yeah Chrome must refuse your request because the standard says:

Terminate these steps if header is a match for one of the following headers: [...]

• Date

Answer 2

You can't. Since you are sending a XHR request it MUST be terminated according to the standard when you set a whole list of prohibited headers:

You'll need to proxy through your originating url or some other work around.
