The documentation for AliasMatch refers to "standard regular expressions" but is there any reference for exactly what syntax is allowed in AliasMatch directives? Is there a non-grouping version of parentheses, where the contents are not saved for later substitutions? Like (?:) in the Python re module. Is there any way to specify an optional group by following it with a question mark such as: AliasMatch "^/a/b/(c/)?d" /x/y/z Thanks, -- Matthew M.
