This is helpful, thanks.
I'm still not quite sure though how would a user react to say 'null'.
It might've been
If-Match: something -> null
or
If-None-Match: something else -> null
Perhaps the user would then check if it was If-Match that was set to
'something'... Or may be in a given web application a user always knows
that a client can only send say If-Match ...
Cheers, Sergey

Request.evaluatePreconditions("something")
If-Match: something -> null // if (functionValue matches headervalue)
If-Match: somethingelse -> non-null
If-None-Match: something -> non-null // if (functionValue doesn't
match headervalue)
If-None-Match: somethingelse -> null
Its basically like an if statement with true returning null and false
returning a Response.
