tomcat 6的配置官方文档：http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html

官方的配置说明：  
  
  
Values for the pattern attribute are madeup of literal text strings, combined with pattern identifiers prefixed by the"%" character to cause replacement by the corresponding variablevalue from the current request and  
response. The following pattern codes aresupported:  
  
  
%a - Remote IP address  
%A - Local IP address  
%b - Bytes sent, excluding HTTP headers, or '-' if zero  
%B - Bytes sent, excluding HTTP headers  
%h - Remote host name (or IP address if resolveHosts is false)  
%H - Request protocol  
%l - Remote logical username from identd (always returns '-')  
%m - Request method (GET, POST, etc.)  
%p - Local port on which this request was received  
%q - Query string (prepended with a '?' if it exists)  
%r - First line of the request (method and request URI)  
%s - HTTP status code of the response  
%S - User session ID  
%t - Date and time, in Common Log Format  
%u - Remote user that was authenticated (if any), else '-'  
%U - Requested URL path  
%v - Local server name  
%D - Time taken to process the request, in millis  
%T - Time taken to process the request, in seconds  
%I - current request thread name (can compare later with stacktraces)  
There is alsosupport to write information from the cookie, incoming header, the Session orsomething else in the ServletRequest. It is modeled after the ApacheHTTP Server log configurationsyntax:  
  
  
%\{xxx\}i for incoming headers  
%\{xxx\}o for outgoing response headers  
%\{xxx\}c for a specific cookie  
%\{xxx\}r xxx is an attribute in the ServletRequest  
%\{xxx\}s xxx is an attribute in the HttpSession  
The shorthandpattern name common (which is also the default) corresponds to '%h %l %u %t "%r" %s %b'.  
  
  
The shorthandpattern name combined appends the values of the Referer and User-Agent headers, each in double quotes, to the common pattern describedin the previous paragraph.
