I am making cross domain ajax requests with html data type. They work OK as I include
Access-Control-Allow-Origin
in the response from the server. Problem is I need to get certain headers from the server's response and whatever I do, response headers apart from "content type" return null.
jQuery does the request, retrieves the response including headers (I can see it from the traffic) but it doesn't parse it.
I have tried using
crossDomain: true
It didn't help. Here is the sample response from the server.
Access-Control-Allow-Origin:*
Cache-Control:private
Content-Encoding:gzip
Content-Length:514
Content-Type:text/html; charset=utf-8
X-MYRESPONSEHEADER:1
If requesting and responding document are on same server
success: function (data, status, xhr) {
totalRows = xhr.getResponseHeader("X-MYRESPONSEHEADER");
works fine. I have also tried to assign $.ajax to a variable like
var jQxhr = $.ajax(.....
I don't see why it wouldn't be parsed since jQuery actually makes the request and gets the response
Any ideas? Am I missing something?
Headers sent to request

Content-Encoding: gzip

Access-Control-Allow-Headers: X-MYRESPONSEHEADER
Access-Control-Allow-Methods: POST
Access-Control-Allow-Methods: GET

You need to add another CORS-specific header in the server response, Access-Control-Allow-Headers
. In this case,
Access-Control-Allow-Headers: X-MYRESPONSEHEADER
