Description Fuwei Chin 2021-06-22 07:09:39 UTC
Nowdays HTTP Trailer gets shipping in all major browsers (Chrome 91, Firefox 89 and Safari 14.1) in order to support Server Timing. see https://caniuse.com/?search=trailer and https://www.w3.org/TR/server-timing/

As part of Servlet 4/5 spec, HTTP Trailer is not currently implemented in Tomcat. I request to add HTTP Trailer to roadmap / feature list.

Tomcat 9.0.x implements the Servlet 4 spec, including HTTP trailer support.

Tomcat 10.0.x implements the Servlet 5 spec, including HTTP trailer support.
