With a Test::WWW::Mechanize::Catalyst instance, I recently had to do the following to send a DELETE:
$mech->request( HTTP::Request::Common::_simple_req( DELETE => $uri ) );
Give that this isn't too unusual for REST, what did I miss?
That I already did that locally (use PIPTest::Mechanize), and that I submitted a wishlist against libwww which is supposed to be fixed in the next release.
I guess Mechanize needs to support it as well though, now that it has support for it in libwww.
