Bug 16189 – XMLHttpRequest::setRequestHeader() should not set certain headers

• Status: RESOLVED
• Resolution: FIXED
• Component: XML

[Julien Chaffraix]

The XMLHttpRequest working draft gives a list of headers that should not be set by setRequestHeader() for security reasons. Currently some of them are missing.

Mozilla checks for all of them except the ones starting with "Proxy-".

Patch & testcase will follow.

Add all the headers specified by the draft (even "Proxy-" headers).

Looks great! Minor coding style issue:

+    static String proxyString;
     
     if (forbiddenHeaders.isEmpty()) {
         forbiddenHeaders.add("accept-charset");
         forbiddenHeaders.add("accept-encoding");
+        forbiddenHeaders.add("connection");
         forbiddenHeaders.add("content-length");
-        forbiddenHeaders.add("expect");
+        forbiddenHeaders.add("content-transfer-encoding");
         forbiddenHeaders.add("date");
+        forbiddenHeaders.add("expect");
         forbiddenHeaders.add("host");
         forbiddenHeaders.add("keep-alive");
         forbiddenHeaders.add("referer");

You could just write    static String proxyString("proxy-"), it will still be initialized only once.

r- to consider style request, but I'll happily r+ with that revision.
