Option Name:reply_header_replace
Default Value:none
Suggested Config:

        Usage:   reply_header_replace header_name message
        Example: reply_header_replace Server Foo/1.0

        This option allows you to change the contents of headers
        denied with reply_header_access above, by replacing them
        with some fixed string.

        This only applies to reply headers, not request headers.

        By default, headers are removed if denied.
