Short and sweet, this should allow us to issue HEAD requests against the API the
/api/v1.0/director/<origin or object>
endpoints. The tagged issue also mentioned making this compatible with our shortcut middleware in the director, but it looks like it already was -- the middleware was agnostic of verbs that weren'tPUT
. My addition to the middleware here explicitly tiesGET/HEAD
requests to the appropriate redirect functions so that other verbs we don't anticipate don't creep in.One thing to note is that if a client who issues a
HEAD
for some resource chooses to follow the redirect, XRootD appears to hang with an open connection. Since that's in XRootD land, I'm considering it outside the scope of this small fix.Closes #754
