One of the points made earlier was that caching/hotlisting heavily
paramterized GET commands can be undesireable - i.e. they tend to bump the
file sizes of hotlists, global histories, etc. I'm glad that you also
agree that hotlisting POSTs is worrisome - though, they are doable - just
store the data blob along with the URL in a structured format. Still, the
loci on control determining allowance of this ought to ultimately rest with
the user.
Conclusions from discussions:
use GET for logical independant tasks/retrieval
currently POSTs should not be hotlisted/cached, though this is doable
session-based transactions suit interactive tasks whereas stateless
transactions suit most paramterized IR tasks
Any others?
Jim.
