Proxing to tomcat with httpd Jean-Frederic Clere Principal Software Engineer / Red Hat What I will cover ● Proxy what and why. ● Protocols – AJP – HTTP/HTTPS (1.1) – HTTP/2 (H2 and H2C) – Others 10/12/22 2 Who I am Jean-Frederic Clere Red Hat Years writing JAVA code and server software Tomcat committer since 2001 Doing OpenSource since 1999 Cyclist/Runner etc Lived 15 years in Spain (Barcelona) – Using SSLValve ● HTTP/HTTPS: – HTTPS might be needed (Encryption/Authentication) – HTTPS on tomcat (openssl again?) – HTTP if you trust your intranet. (really?) ● Other reasons: – HTTP is more
