>>> Vanity (server, x-powered-by, via)

gosh, no.

server is no vanity, server is needed to know WHO THE HELL responded you (we are in a very messy cdn selectors + cdns + application layers depending on non obvious rules on (sub)domain and cookies).



While working on a HTTP server in 2007 I discovered removing the "Server" header significantly delayed the render time in Firefox.

So beware of unexpected side-effects!


That is supposed to be handled by Host header. Server etc. provides at most redundant debugging info.


The Host header is in de request, it should not occur in the reply (as the article states)
