当日志说它已经将请求重写为php文件时，Apache仍会加载测试页面

Question

I have configured an apache virtualhost to point localhost to /var/www/html/mysite/public which contains a htaccess file rewriting all request to handle.php in the same dir, I know the htaccess file works because syntax errors in it cause internal server errors to appear

But when I go to localhost/ I get the apache test page, I enabled LogLevel alert rewrite:trace3 to see what was going on and the log shows that it's trying to rewrite the request to handle.php but... not? What is going on here

handle.php just contains die('test'); so I'd know if it actually used that file

This was because my apache was in a docker container and docker was preventing apache reading dirs that didn't exist, strace was extremely useful in debugging this. See https://github.com/moby/moby/issues/1295
