HTTPS to HTTP rewrite

A server's response? Is the response a 30x redirect or URLs in the payload?

when HTTP_REQUEST {
    HTTP::header remove Accept-Encoding
    STREAM::disable
}
when HTTP_RESPONSE {
    if { ( [HTTP::header exists Location ) and ( [HTTP::header Location] contains "https://" ) } {
        HTTP::header replace Location [string map -nocase {"https://" "http://"} [HTTP::header Location]]
    }
    if { [HTTP::header Content-Type] contains "text" } {
        STREAM::expression {@https://@http://@}
        STREAM::enable
    }
}

when I copy this irule I get

01070151:3: Rule [/Common/HTTPS-HTTP-Redirect] error: /Common/HTTPS-HTTP-Redirect:6: error: [parse error: PARSE missingBracket 114 {missing close-bracket}][{ ( [HTTP::header exists Location ) and ( [HTTP::header Location] contains "https://" ) }]

Forgot the trailing closing square bracket "]" in the HTTP::header exists Location statement.
