Hi,
i have latest vesrsion of xampp, (xampp for windows 7.4.7).
And i have some suggestions for developers, for next versions. HTTP2 protocols is more eficient than http1.1, so i think, xampp should use http2 protocol by default.
My suggestion for next releases (by default):
1º, Activate http2 --> Uncomment "LoadModule http2_module modules/mod_http2.so" in httpd.conf and file http-ssl.conf should have this line: "Protocols h2 h2c http/1.1" after "<VirtualHost _default_:443>".
2º Update Certificate Date (Is valid to 09-11-2019), see C:\xampp\apache\conf\ssl.crt
3º In httpd-ssl --> Change line ServerName www.example.com:443 to ServerName localhost:443
I'm not sure if this is the correct process for activating http2, but certainly xampp developers will think about it ... right?
