You neglected to include this in your  out of context quote.

Description: Specifies a list of rewrite rules at virtual host or context level. A rewrite rule is comprised of one RewriteRule directive and optionally preceded by multiple RewriteCond directives.

• Each directive should take only one line.
• RewriteCond and RewriteRule follow Apache's rewrite directive syntax. Just copy and paste rewrite directives from your Apache configuration files.
• There are minor differences between LiteSpeed and Apache mod_rewrite implementation:
  • %\{LA-U:variable\} and %\{LA-F:variable\} are ignored by the LiteSpeed rewrite engine
  • two new server variables are added in the LiteSpeed rewrite engine: %\{CURRENT_URI\} represents the current URI processed by the rewrite engine and %\{SCRIPT_NAME\} has the same meaning as the corresponding CGI environment variable.
