RewriteLog

Rewrite Engine Logging Target
Syntax: RewriteLog A
Example: RewriteLog logs/rewrite_log
Since: Apache 1.2

This directive sets the file of the dedicated rewriting engine log file. It should appear where it cannot be used for symbolic link attacks on a real server (that is, a location where only ``root'' can write). If the file name does not begin with a slash (``C''), then it is assumed to be relative to the server root. If file begins with a bar (``|''), then the following string is assumed to be a file path to an executable program to which a reliable pipe can be established.
