so it can "replace" header, is should be able to "unset" header
header() is to "low level"
better to implement these functions:
header_set($name, $value [, response_code]) // replace or set new one
header_add($name, $value) // "append" new one
header_unset($name, [, $count]) // remove all, or N
these functions will work, until header_sent(), after which will get
warnning.
it's just like operating on an array/table (but allow dup key)

If you can <i>modify</i> headers using the header() function, they
can't be sent already, can they?
At least with some types of headers, this works.
So I assume that headers are buffered at least until the document
output has begun.

Blind shot - this is impossible because headers get sent as soon I they
are encountered and thus you can override them by sending one more yet
cannot remove what you have already sent. I might be wrong, though.
If I'm not then lots close this one.

Sometimes it would be very handy to be able to remove a http header
that has already been set (for example, by the session module). Even
though header() allows me to replace a header, there is no way to
completely remove it.
Proposal:
header("Pragma:") could be used to remove a Pragma header - i.e. a
header given with no parms would remove the header.
Better:
New function like remove_header()
