All logs are enabled in the Caching Proxy default configuration. They are stored in the logs/ subdirectory of the installation directory. The default paths are the following:
Each log file name is a combination of the base name and a date suffix in the form .Mmmddyyyy, for example, proxy.Feb292000.
Logs are stored in the common file format by default. A combined log format is also available and can be set by adding the following line to the proxy configuration file (ibmproxy.conf).
LogFileFormat combined
The combined log format is similar to the common format but has added fields that show the referrer, the user agent, and cookie information. Local time format is the default time format.
By default, all access requests are recorded in the appropriate access log, and no access information is recorded in the system log. Error log information is written to the error log only, and event log information is written to the event log only.
In the default configuration, logs are not archived or deleted.
