+      requests.
+    * :paramval:`this_domain_only` - Send the Strict-Transport-Security header

+    * :paramval:`include_subdomains` - Send the Strict-Transport-Security header
+      along with the includeSubDomains flag, which will apply the security change
+      to all subdomains. This is especially useful when combined with an
+      :param:`attachment_base` that exists as (a) subdomain(s) under the main
+      Bugzilla domain.
