Attributes are simply request-scoped object references that are used to
both pass you extra information, and for you to pass things around an
individual request.

The request headers are separate - these are actually sent with the
request by the client. Once you have them they are already sent over the
wire so in that respect size doesn't matter. They don't automagically
get sent back - the response has a separate set of Headers you can use
to do that.

Relevant methods:

javax.servlet.ServletRequest.getAttribute() (et al.)
javax.servlet.http.HttpServletRequest.getHeader() (et al.)
javax.servlet.http.HttpServletResponse.setHeader() (et al.)

Ross
