www-servers/caddy: add new USE flag - events_handlers_exec
Compiles caddy with events.handlers.exec module[1] This module lets user 'exec'ute arbitrary command with args when some events occur in Caddy.[2] Example use: Run a script which notifies (via mail/telegram etc) web admin when some reverse_proxy's upstream becomes healthy/unhealthy or when something goes wrong while obtaining/renewing TLS certificate automatically. [1] https://caddyserver.com/docs/modules/events.handlers.exec [2] https://caddyserver.com/docs/caddyfile/options#event-options Signed-off-by: Rahil Bhimjiani <[email protected]> Closes: gentoo#35232 Signed-off-by: Zac Medico <[email protected]>
