 {{{
 #!CommitTicketReference repository="" revision="24915"
 Additional checks when evaluating the safety of an HTTP request, to avoid
 false negatives.

  * Check if the host is considered a safe redirect host.
  * Check if the host is another domain in a multisite installation.
  * Add a filter to control this.

 This only occurs when the DNS resolution of a domain points elsewhere in
 an internal network, but only internally (and has its own public IP
 outside the network). This could be considered a bad configuration.

 fixes #24646.
