RewriteLock [ filename]
Default
None
Context
server config, <Global>, <VirtualHost>
Module
mod_rewrite
Compatibility
1.2.6rc1 and later
The RewriteLock directive sets the filename for a synchronization lockfile which mod_rewrite needs to communicate with RewriteMaps of type fifo. Set file to a local absolute path (not on a NFS-mounted device) when you want to use a rewriting FIFO. It is not required for other types of rewriting maps.
