Note that this compares the first three chars case-*sensitively*,
while the rest is insensitive. Header names are intended to be
insensitive.
I'd recommend just dropping the "optimization" of initially checking
the first 3 characters. The string compares are going to be *real*
fast if the first 3 chars do not match (since they'll exit after
checking just a few chars). And relative to getting those headers from
the network, the cycles savings is moot.
*cough* premature optimization *cough*
:-)
