Subject HOWTO remove username/password from logging to tomcat logs
Date Fri, 26 May 2006 13:35:38 GMT
 How do I control the logging of username/password in tomcat logs when a user logs into the
tomcat website. There are no logging statements  in  my servlet  to print this data and there
is no code to catch the login request . Each time a user logs into the website , the username
and password are logged.     I am running tomcat 4.1 on debian with  Tomcat/Apache JK2 Connector
and log4j.     I am using  .Form Based Authentication using Memory Realm via tomcat-users.xml
file.   I have also noticed that when I upload a file  using multipart/form data on http Post
request to servlet, the complete contents of the file gets logged in the tomcat logs in the
same way.   The log entry looks lilke a dump of the http data.   I have been googling the
Internet trying to solve this one and looking through the tomcat docs but cannot find any
place where the logging level controls this data in http content from dumping to the tomcat
logs.   Any ideas would be appreciated.


Here is the contents of the statement I am trying to remove in my catalina.log that appears
when I login as username "demo" and password "dddd".
