Syntax
RewriteLock lockfile
It requires only one argument. lockfile, is traditionally is the path to a file. However, in IIS Mod-Rewrite and Apache for windows, the locking synchronization object is a MUTEX, and therefore lockfile can be also either path to a non-existing file or any other plain name not related to the filesystem.
