Request set Request Header() skips blank headers
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release) Build ID: 20130917102605 Steps to reproduce: During the development of our application, which runs under Firefox, we thought it would be a good idea to send a blank header for development purposes. This header doesn't make it through. var xhr = new XMLHttpRequest(); ... xhr.setRequestHeader('my-header', ''); Here's a curl script that does the same thing: curl -k -H "my-header;" https://127.0.0.1/test.php test.php: <?php print_r(apache_request_headers()); ?> Output: Array ( [User-Agent] => curl/7.27.0 [Host] => 127.0.0.1 [Accept] => */* [my-header] => ) Actual results: Array ( ... [my-header] => ) is missing. Expected results: Array ( ... [my-header] => )
Hm, we are removing the header if the header value is empty, https://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/http/nsHttpHeaderArray.cpp?rev=aceb8d1e6eba#18 But it doesn't comply with the spec. http://xhr.spec.whatwg.org/#the-setrequestheader%28%29-method > Note: An empty string represents an empty header field value.
