The XMLHttpRequest method getResponseHeader() returns the string containing the text of a particular header's value.

If there are multiple response headers with the same name, then their values are returned as a single concatenated string, where each value is separated from the previous one by a pair of comma and space. The getResponseHeader() method returns the value as a UTF byte sequence.

Note: The search for the header name is case-insensitive.

If you need to get the raw string of all of the headers, use the XMLHttpRequest.getAllResponseHeaders method, which returns the entire raw header string.

Implementation

external String? getResponseHeader(String name);
