Subject Re: error count for "http connector" and "localhost/ default context" seem to increment for no reason: mbean bug?
Date Fri, 01 Jul 2005 21:42:58 GMT
The errors are almost certainly 404s in response to the browser's 
request for favicon.ico every time you request a page. The Tomcat distro 
does not include a favicon.ico hence the 404 response.
