chrome extension: refuse header "date" in ajax request

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开发者_StackOverflow社区 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?

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

Reference: http://www.w3.org/TR/XMLHttpRequest/#the-setrequestheader-method

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.

Its lame because if you use Firefox and the RestClient you can do it. But you can't if you use Chrome and the "Advanced Rest Client"
