php - Laravel Public vs Storage directories for audio files -

i little bit confused in directory should put .mp3 files in laravel 5. public/ , first choice mp3 can considered media (like images stored there) storage/app , according docs directory kind of recommended purpose. i don't mind being able url of these audio files since serve stream (to somehow prevent downloads, lol). any advice? thanks. guess depends on whether want direct public access or not. public/ simpler. in there can link directly. js or css or images resources. storage/app more secure, no way access directly. that's use (actually think i'd storage/app/audio specific) have more control on how accessed.

application accessible on tomcat http port. application when accessed web server(apache http server) gives bad gateway error. worker.properties(apache http server) & server.xml(tomcat) tuned well. socket/connection timeout 20 sec on both sides. jk.log shows below error. enter image description here the error says tomcat not accepting connections. how come @ same time, application accessible on http. on tomcat side dont see errors in log. you use different ports http connection (default 8080) , ajp connection (default 8009). can check exact values in conf/server.xml . your error indicates there problems between httpd , client (firewall, slow connection etc.). try remove timeouts, worker.ajp13.socket_timeout=3 . ( https://tomcat.apache.org/connectors-doc/common_howto/timeouts.html ) make sure ports not blocked possible firewalls. ubuntu, ufw (uncomplicated firewall) used open ajp connections: ufw enable && ufw allow 8009 .
