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.
