Mark Thomas <ma...@apache.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEEDINFO |RESOLVED Resolution|--- |INVALID --- Comment #9 from Mark Thomas <ma...@apache.org> --- This is not a Tomcat issue. I have manually tested this (with Telnet) and Tomcat happily accepts the following request: GET /tomcat.svg HTTP/1.1 Host: localhost:8080 If-Modified-Since: Mon, 03 May 2021 20:24:44 GMT If-None-Match: W/"67795-1620035809000" and correctly returns a 304 response. It is clear from the headers in the provided attachments that the application has at least one component providing caching. I suspect the issue is somewhere in that code. Please do not re-open this issue unless you can provide a valid HTTP request that incorrectly generates a 400 response when sent to a clean Apache Tomcat install. -- 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
