hi to everybody,
here is a table resuming the behaviour of current wget version (soon to be
1.11) and wget 1.10.2 regarding HTTP HEAD requests. i hope the table will be
useful to determine whether the currently implemented logic is correct.
please notice that recently micah changed the behaviour of
--no-content-disposition option, turning it on by default. that is, by default
wget will not consider Content-Disposition header in HTTP resource retrieval.
