TYPO3 Core

It probably is possible.

I committed the change suggested above in the T3DD06 repository.

In typo3/sysext/cms/tslib/class.tslib_fe.php on line 1770.

The only question is whether we want something more than just strftime() markers. Personnally, I find this fully satisfying.

Moved logfile_dir out of the strftime() call.

Proposed update to the description of the config.stat_apache_logfile parameter in the TSRef:

This the filename of the logfile in the directory $TYPO3_CONF_VARS["FE"]["logfile_dir"] (localconf) on the server where TYPO3 writes to the apache logfile. The directory defined by $TYPO3_CONF_VARS["FE"]["logfile_dir"] must exist and be writable. It can be relative (to PATH_site) or absolute, but in any case it must be within the regular allowed paths of TYPO3 (meaning for absolute paths that it must be within the “lockRootDir” set up in TYPO3_CONF_VARS).
It is possible to use date markers in the filename, as per the PHP function strftime(). This will enable a natural rotation of the logfiles. For example, typo3_%Y%m%d.log will create daily log files.
Make sure that the web server's user has the rights to write in the logfile directory.

Added to SVN.

The TSRef has not been updated accordingly. See note with proposed modified description of stat_apache_logfile.

I already discovered that last week. Will commit during this week...

Great. Thanks.
