Fix: Restore Local Request Handling for SSL Verification for https_local_ssl_verify filter

[Debarghya-Banerjee]

Trac Ticket: Core-51767

Issue

In WordPress 4.6, the $args['local'] element was removed from HTTP API requests, which caused the https_local_ssl_verify filter to malfunction.

Solution

This update restores the expected behaviour by checking if a request is local using:

• The REMOTE_ADDR (127.0.0.1, ::1).

• The HTTP_HOST (localhost, 127.0.0.1).
