Hi Mark Thomas and Tomcat Team, We have a strange issue with Tomcat 9.0.72. All 204 response does not complete in firefox. It works in the Chrome browser. If we downgrade the tomcat version is less than .72. Everything works on all browsers.
https://github.com/apache/tomcat/commit/b7a21f2d6fa73f932e9d01874936e5b6b32503fb Tomcat Change Log: 66442 <https://bz.apache.org/bugzilla/show_bug.cgi?id=66442>: When an HTTP/2 response must not include a body, ensure that the end of stream flag is set on the headers frame and that no data frame is sent. (markt) You can see the fist request does not complete at all: [image: image.png] Can you please check this in firefox 2? We tried the older version of firefox 2 same issue.
