My implementations of server/client use the META field to communicate
between the server and the user (through the client) - and in many cases,
the value in META *is* limited and well defined by the current spec.
See the 10 and 11 status codes - the prompt that the user should be shown
is the value of the META field.
The 3x status codes - the META is the location the server is redirecting
the client to.
Etc. (there are other places that META has specific meaning - even if the
exact value is left up to the implementor , like on status 10 - as the spec
says, the meaning of META is <STATUS> dependent)
Does that help?
