Hotlinking to any repository browser (whether Phabricator, Quickgit,
WebSVN or anything else) on KDE infrastructure is not supported under
any circumstance. Our web servers are configured to block some forms
of this already.

Repository browsers are extremely expensive resource wise, compared to
static file serving, and one can expect something like Appstream
metadata to receive quite a few hits, therefore something properly
setup for this should be done.

Please file a sysadmin ticket once you've determined what the best way
is to do this.
