Servers that don't support it ignore it, because RFC-2616 doesn't provide an error code to mean "I don't understand that Upgrade:". (I just tried it on Apache 1.3.9 and 1.3.12, NES 3.6, and IIS 5.0; they all behaved exactly the same with and without "Upgrade: foo".) This means that a client that sends the Upgrade: all the time won't break anything; it will cost a few extra bytes, but not the extra round trips you're talking about. -- /================================================================\ |John Stracke | http://www.ecal.com |My opinions are my own. | |Chief Scientist |===============================================| |eCal Corp. |The cheapest, fastest, most reliable components| |francis@ecal.com|of a computer system are those that aren't | | |there.--Gordon Bell | \================================================================/
