Presumably, Servlet 4 will require Java 8. Does that mean that HTTP/2 with the NIO connectors will only be available with a higher JRE version? > h2c support (HTTP/2 over a cleartext channel via HTTP upgrade > rather than TLS) is also on the TODO list.

Jim Riggs's (reprise, I believe) presentation at ApacheCon about how "mod_php needs to die" (paraphrasing) advocates more extensive use of mod_proxy_* to physically separate the web tier from the application tier, in a way that more closely resembles how Java webapps are deployed. Perhaps if the world starts listening to the Jim Riggses of the world, the shortcomings of mod_proxy_websocket and friends will become more apparent. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJVVjm/AAoJEBzwKT+lPKRY6ZAQAK5BSg+ilfOs6T9hNtX91h/x /aZm6dSzncJMyP7gZ1FX2J9wlq+P99lx8FZEkO4gJOVpi/uGqP+nYvZoKydTQ8sb WbMVLMZBjrR+cP0gnX1sMELKQD7Llq8InYblfY9sE3s+wf8BKX4W2NXYei51vQv9 2k9tdgp7k/ibMu4jbSTnuqrFy67eTYLOJEwqXH6F0zsItwCqGX2njFH/ra4i9oU3 SMyIPNYngC3SYKurTve1cxZpU4J3FuWx/KcLIEIePMNUKU/Ner77tizqNi/xil7b Dw7VPgPVnD9tavznCd7Fz9HMhi/giG+X1rK9UJ7tnkP8kpdC+RgM0JPTB6nqEgvW uMJfXWagVcU+Rtmt8smWOpV1VlEMsorqJ8I4OS5DTACt0aFVRsjSXNKRaeLBUUje JPqRFmHKESksIWwJAnWY7BderGPegWTreDreeAQcvy+6ZkkWxxL925iPd+2aDBhP hU/p65YnqqPp8qc+HYwtV5aC1UE1CcKXh8VepFnb9z3H7wUe8hSu1PcxqHUhwJXl OMDjfCGrGs5egdWXqZgQSQKfE9nnhCZqOsKSY+Q5NhBs2P6TKhwv+i0VzdzNKyW8 jKjaoiE3CQEeb1YcPhT7JywChCdL9HKU1xlpY4LfTdIsmz/YngMi4DyWvaAL7dPX qY7fh/2rVnqrZXm52SzO =bawW -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
