I now have logs from both the Apache server and Tomcat. I'm a little unsure how to interpret these log files. It shows that Tomcat does serve the file correctly and it is Apache that appears to do something odd when Tomcat returns a 304 response code.
Apache Access Log xx.xx.4.58 - - [17/Jul/2008:12:31:38 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:12:31:42 +0100] "GET /css/global.css HTTP/1.1" 200 2352 xx.xx.4.58 - - [17/Jul/2008:12:31:48 +0100] "GET /css/global.css HTTP/1.1" 200 7323 xx.xx.4.58 - - [17/Jul/2008:12:31:51 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:12:33:01 +0100] "GET /css/global.css HTTP/1.1" 200 7248 xx.xx.4.58 - - [17/Jul/2008:13:42:14 +0100] "GET /css/global.css HTTP/1.1" 200 7323 Tomcat Access Log xx.xx.4.58 - - [17/Jul/2008:12:31:38 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:12:31:42 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:12:31:48 +0100] "GET /css/global.css HTTP/1.1" 200 7323 xx.xx.4.58 - - [17/Jul/2008:12:31:50 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:12:33:01 +0100] "GET /css/global.css HTTP/1.1" 304 - xx.xx.4.58 - - [17/Jul/2008:13:42:14 +0100] "GET /css/global.css HTTP/1.1" 200 7323 Little unsure about how the 4th request at 12:31:51 on Apache was served by Tomcat at 12:31:50. I've double checked this and it is correct. Tim.. Tim Redding wrote: > > > Thanks for the quick reply. I've enabled the AccessLogValve. I've just > gotta wait for it to start playing up again.
