With these flags the admin can gain complete control of IceWarp Web Server behavior.
Flags need to be separated from the regex with space and surrounded in "[]" brackets. Such as:
[L,R]
Available flags are:
[R]edirect - redirect instead of rewrite
[L]ast - do not process other rewrite this is the last one
[F]orbidden - the user will receive 403 Forbidden message when accessed the URL
[C]hain - if the rule is not matched, skip all following rules containing [C] flag
[V=VARNAME] - match to server variable instead of URI
[] - void flag - force processing following rules
If no flag is specified, the default flag is [L]. If rewrite is matched no other rule will be processed, unless you specify void flag []. So the behavior is the same for non regex rewrites (redirects).
