Flags

• C (chained with next rule)
• CO=cookie (set specified cookie)
• E=var:value (set environment variable var to value)
• F (forbidden - sends a 403 header to the user)
• G (gone - no longer exists)
• H=handler (set handler)
• L (last - stop processing rules)
• N (next - continue processing rules)
• NC (case insensitive)
• NE (do not escape special URL characters in output)
• NS (ignore this rule if the request is a subrequest)
• P (proxy - i.e., apache should grab the remote content specified in the substitution section and return it)
• PT (pass through - use when processing URLs with additional handlers, e.g., mod_alias)
• R (temporary redirect to new URL)
• R=301 (permanent redirect to new URL)
• QSA (append query string from request to substituted URL)
• S=x (skip next x rules)
• T=mime-type (force specified mime type)
