Formatting OC4J access logs

OC4J can be configured to log its web accesses to a specified access-log file.

The format of the log entry can be customized according to the documentation here:

http://download.oracle.com/docs/cd/B25221_04/web.1013/b14432/website.htm#BABFGJHD

Some format tokens that are mentioned, but not really called out are $cookie and $header.

Using these tokens, you can ask OC4J to inject the specified cookie/header value into the access-log.

For example, if you wanted to log the value of the JSESSIONID cookie for each request, you'd configure the format string as follows:

<access-log path="../log/default-web-access.log" format="
$ip - $user '$request' $status $cookie:JSESSIONID" />

When OC4J runs, it will log entries in default-web-access.log according to the pattern that was specified:
