Actually loads port 80 Blink: Removes the port and navigates WebKit: Removes the port and navigates location.port = 0 Gecko: Throws Presto: Noop Trident: Sets port to 0 and navigates to it.

I prefer the Blink behavior for the special case as it is consistent across objects. (Assuming it would actually succeed loading if I have something hosted on port 0.) 95292 3 annevk 2013-10-24 10:50:10 +0000 https://github.com/whatwg/url/commit/53dae545e386f26208b8038de55a918ffe421ac8 97663 4 annevk 2013-12-16 14:28:04 +0000 So bz pointed out that what everyone does here is not very useful and that having "" string mean the default port (ie removing the port) is more useful. Reading comment 1 again it seems that is what Blink/WebKit do for location.port today. So maybe the specification was not that bad here. 97664 5 bzbarsky 2013-12-16 14:37:19 +0000 > Assuming it would actually succeed loading if I have something hosted on port 0 It wouldn't, since 0 is not a valid port number for any of the protocols we care about. 98068 6 annevk 2014-01-07 11:19:57 +0000 In https://bugzilla.mozilla.org/show_bug.cgi?id=930450 Gecko decided that the empty string should not be special cased (it will result in .port === ""). To match that I should remove step 2 in the setting algorithm here: http://url.spec.whatwg.org/#dom-url-port 98137 7 annevk 2014-01-08 17:33:56 +0000 https://github.com/whatwg/url/commit/def2ff3b3881fa9f4cf8ee2b6d622a9c5209c0c3
