Fast Response on Remote Server Slow Response on Local Server
Posted: Wed Mar 20, 2019 8:16 pmHi, I'm having trouble using ESP8266 on a local server but not remote servers. If I GET request a remote server with PHP the response is very fast. If I try to execute the exact same PHP script on a local server (I've tried Windows XAMPP installation and a Raspberry Pi with manually installed Apache and PHP and I've tried two different networks, problem is the same across all).
All the PHP file I'm trying to execute is doing is printing a single character and nothing else. Literally:
If I GET request this from somedomain.com/a.php the response is instant.
If I GET request 192.168.1.10/a.php (local server IP) it takes over 5 seconds for the character to be printed. Requesting HTML pages with no PHP is instant on local server, it is only PHP code that is slow.
My Sketch Code:
