Well
merlyn gave the best answer, but you can actually
subclass off of LWP if you need to. What you can do is
create a new protocol. The package-name needs to be of
the form LWP::Protocol::foo, and it needs to inherit from
LWP::Protocol. To get a sample, take a look at how
LWP::Protocol::https is implemented, subclassing off of
http.
None of which you really need to know unless you are trying
to figure out how LWP works, or are trying to write a new
scheme.
ObRandomThought: Having read the code, I am wondering why the heck
they have the hack to pass news to nntp in the implementor
method of LWP::Protocol. Why not just have a trivial
LWP::Protocol::news module that just inherits from
LWP::Protocol::nntp?
