--- Comment #2 from Megha Talathi <meghatalath...@gmail.com> --- Thanks for the quick reply, Mark! That's helpful to know. But still, my concern is not clear. Can you please help with this? Concern: The same code works in the lower version under Tomcat 9.x.x. To be specific, it is working in Tomcat 9.0.35 and Tomcat 9.0.56. i.e, the response header like the one below is sent: "Last-Modified" : "木, 11 5月 2023 21:15:43 JST" But I recently upgraded my Application to Tomcat 9.0.82 and Tomcat 9.0.84 with the same configuration XML, and there it started giving errors. So, does that mean in Tomcat 9.0.35 & Tomcat 9.0.56 does not check rules under 'RFC 9110, section 5.5'? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
