Metacat

Fixed formatting problem in a documentation file.

add section about importing self-signed certificates into the Java keystore (now that we use strict verification on the java client side when calling replication endpoints).

a few additional notes about Metacat replication configuration.

It looks like jk.conf and workers.properties were moved in the scripts dir: update the install docs accordingly.

Fixed a minor typo in the tomcat config section.

add note about https://redmine.dataone.org/issues/2451 to the documentation

update docs to match node registration behavior: we do not assign them nodeIds at registration

Set mime type on images.

Set mime type.

Use 'a2dissite' to disable the default site (not 'a2ensite').
