=head1 Notes


=head2 Limited Functionality under Threaded MPMs

Note that under threaded MPMs, some of the read/write accessors, will
be able to set values only before threads are spawned (i.e. before the
C<L<ChildInit
phase|docs::2.0::user::handlers::server/C_PerlChildInitHandler_>>).
Therefore if you are developing your application on the non-threaded
MPM, but planning to have it run under threaded mpm, you should not
use those methods to set values after the ChildInit phase.

The affected accessor methods are marked as such in their respective
documentation entries.








=head1 Unsupported API

C<Apache::ServerRec> also provides auto-generated Perl interface for a
few other methods which aren't tested at the moment and therefore
their API is a subject to change. These methods will be finalized
later as a need arises. If you want to rely on any of the following
methods please contact the L<the mod_perl development mailing
list|maillist::dev> so we can help each other take the steps necessary
to shift the method to an officially supported API.




=head2 C<addrs>

Get the addrs value

  $addrs = $s->addrs();

=over 4

=item obj: C<$s>
( C<L<Apache::ServerRec object|docs::2.0::api::Apache::ServerRec>> )

=item ret: C<$addrs>
( C<L<Apache::ServerAddr|docs::2.0::api::Apache::ServerAddr>> )

Returns the addrs setting.

=item since: subject to change

=back

META: this methods returns a vhost-specific Apache::ServerAddr object,
which is not implemented at the moment. See the struct server_addr_rec
entry in httpd-2.0/include/httpd.h for more information. It seems that
most (all?) of the information in that record is available through
other APIs.





=head2 C<lookup_defaults>

Get the lookup_defaults value.  MIME type info, etc., before we start
checking per-directory info.

  $lookup_defaults = $s->lookup_defaults();

=over 4

=item obj: C<$s>

=item ret: C<$lookup_defaults>
