```
public class AccessLogValve
extends ValveBase
implements AccessLog
```
Implementation of the Valve interface that generates a web server access log with the detailed line contents matching a configurable pattern. The syntax of the available patterns is similar to that supported by the Apache HTTP Server mod_log_config module. As an additional feature, automatic rollover of log files when the date changes is also supported.

Patterns for the logged message may include constant text or any of the following replacement strings, for which the corresponding information from the specified Response is substituted:
- %a - Remote IP address
- %A - Local IP address
- %b - Bytes sent, excluding HTTP headers, or '-' if no bytes were sent
- %B - Bytes sent, excluding HTTP headers
- %h - Remote host name (or IP address if enableLookups for the connector is false)
- %H - Request protocol
- %l - Remote logical username from identd (always returns '-')
- %m - Request method
- %p - Local port
- %q - Query string (prepended with a '?' if it exists, otherwise an empty string
- %r - First line of the request
- %s - HTTP status code of the response
- %S - User session ID
- %t - Date and time, in Common Log Format format
- %u - Remote user that was authenticated
- %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)
In addition, the caller can specify one of the following aliases for commonly utilized patterns:
- common - %h %l %u %t "%r" %s %b
- combined - %h %l %u %t "%r" %s %b "%{Referer}i" "%{User-Agent}i"
There is also support to write information from the cookie, incoming header, the Session or something else in the ServletRequest.
It is modeled after the Apache HTTP Server log configuration syntax:
- %{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
- %{xxx}t xxx is an enhanced SimpleDateFormat pattern (see Configuration Reference document for details on supported time patterns)
Log rotation can be on or off. This is dictated by the rotatable property.

For UNIX users, another field called checkExists is also available. If set to true, the log file's existence will be checked before each logging. This way an external log rotator can move the file somewhere and Tomcat will start with a new file.

For JMX junkies, a public method called rotate has been made available to allow you to tell this instance to move the existing log file to somewhere else and start writing a new log file.

Conditional logging is also supported. This can be done with the conditionUnless and conditionIf properties. If the value returned from ServletRequest.getAttribute(conditionUnless) yields a non-null value, the logging will be skipped. If the value returned from ServletRequest.getAttribute(conditionIf) yields the null value, the logging will be skipped. The condition attribute is synonym for conditionUnless and is provided for backwards compatibility.

For extended attributes coming from a getAttribute() call, it is you responsibility to ensure there are no newline or control characters.
