I understand your perspective but you cannot compare two entirely
different things. Don't forget that most modern web apps are 99% driven
by JavaScript. If the server returns a 404, JavaScript is still unable
to read the initial HTTP status code. Think about it :)

That would work but is an overhead, a redundancy. Why add another meta
tag if the status code is already in the HTTP header??

Yes, it's interesting why nobody has suggested this before. There is
always a first time. Probably I am the first to ask for this feature
because I've been working heavily with SPA's and node.js in the recent

Really, it would be awesome if JavaScript could read the HTTP status code!
