iRule not parsing correctly... hidden spaces?

Pulling hair out on this one.... trying to find a hidden space? Trailing space? Bad juju?

 

When inputting this iRule straight from Notepad++ - I get this nasty bit of NON-HELPFUL information:

 

01070151:3: Rule [/Common/site1.abc.com_redirect2] error: /Common/site1.abc.com_redirect2:1: error: [undefined procedure: When][When HTTP_REQUEST { Switch –glob [string tolower [HTTP::uri]] { “/” {HTTP::redirect "; } “/v2” {HTTP::redirect "; } default { do nothing } } }]

 

The actual iRule is this:

 

When HTTP_REQUEST { Switch –glob [string tolower[HTTP::uri]] { “/” {HTTP::redirect "; } “/v2” {HTTP::redirect "; } default { do nothing } } }

 

Any help is much appreciated.

    I think the notepadd ++ is getting rid of some CR/LF characters.

    Try this for iRule:

    when HTTP_REQUEST {
    switch -glob[string tolower [HTTP::uri]] {
        "/" { 
            HTTP::redirect "http://site1.abc.com/main"
        }
        "/v2" {
            HTTP::redirect "http://site1.abc.com/second/api/v2" 
        }
        default { 
            log0.notice "do nothing"
        }
    }
}

    I've removed the capitalisation, semi-colons and for some reason the hyphen used before -glob wasn't the correct character: 

    when HTTP_REQUEST {
    switch -glob[string tolower [HTTP::uri]] {
        "/" { 
            HTTP::redirect "http://site1.abc.com/main"
        }
        "/v2" {
            HTTP::redirect "http://site1.abc.com/second/api/v2" 
        }
        default { 
            log0.notice "do nothing"
        }
    }
}
