问题
I have been trying to setup my tomcat 9 rewrite valve (on global level) without success, followed every tutorial I have found on the internet, but no matter how i configure my rewirte.config the valve simply does NOT work.
So I write the simplest rewrite.config I can think of, which contains only a single line:
RewriteRule ^test$ manager/test.jpg
So this rule simply means to rewrite http://localhost:8080/test to http://localhost:8080/manager/test.jpg
This file is placed inside $CATALINA_HOME/conf/Catalina/localhost I have verified that the valve is loaded properly in the localhost.2018-08-30.log log file:
30-Aug-2018 14:32:43.530 FINE [main] org.apache.catalina.valves.rewrite.RewriteValve.parse Add rule with pattern ^test$ and substitution manager/test.jpg
However when I restarted tomcat and tested it, the URL http://localhost:8080/test gave me a 404 error while the URL http://localhost:8080/manager/test.jpg loads the actual image correctly.
The access log shows:
127.0.0.1 - - [30/Aug/2018:14:39:50 +0800] "GET /test HTTP/1.1" 404 1078
127.0.0.1 - - [30/Aug/2018:14:42:34 +0800] "GET /manager/test.jpg HTTP/1.1" 304 -
So what did I miss?
