function internal_nodes_url_outbound_alter in Internal Nodes 7

Implements hook_url_outbound_alter().

Disabled by default in the configuration: admin/config/search/internal-nodes This function is called many times per page, so I've tried to make it as efficient as possible. Multiple if statements are ordered to reduce overall cpu cycles for most use cases.
