Redirect HTTP::uri doesn't work properly.

Hi Diez,

actually you've already answered your question yourself... 🙂

if a request for

http(s)://mail.acme.com/mail

[if]

if { [HTTP::uri] starts_with "/mail" } then {  
    HTTP::redirect https://usa.acme/webmail_exchange
}   
if { [HTTP::host] equals "mail.acme.com" } then {
    HTTP::redirect https://mail.acme.com/webmail_zimbra
}

... then you would send two redirects for the very same request. This will result in an iRule exception (keep an eeye on your LTM logfile) and terminate the TCP connection before the redirect is send.

To solve your problem you could either issue a

return

HTTP::redirect

HTTP::respond

when HTTP_REQUEST {
    if { [HTTP::uri] starts_with "/test" } then {
        HTTP::redirect "https://usa.acme.com/something"
        return
    } 
    if { [HTTP::uri] starts_with "/mail" } then {
        HTTP::redirect "https://usa.acme/webmail_exchange"
        return
    }
    if { [HTTP::host] equals "acme.com" } then {
        HTTP::redirect "https://usa.acme.com"
        return
    }
    if { [HTTP::host] equals "mail.acme.com" } then {
        HTTP::redirect "https://mail.acme.com/webmail_zimbra"
        return
    } 
}

... or by creating an collision free rule set...

when HTTP_REQUEST {
    if { [HTTP::host] equals "acme.com" } then {
        if { [HTTP::uri] starts_with "/test" } then {
            HTTP::redirect "https://usa.acme.com/something"
        } elseif { [HTTP::uri] starts_with "/mail" } then {
            HTTP::redirect "https://usa.acme/webmail_exchange"
        } else {
            HTTP::redirect "https://usa.acme.com"
        }
    } elseif { [HTTP::host] equals "mail.acme.com" } then {
        if { [HTTP::uri] starts_with "/test" } then {
            HTTP::redirect "https://usa.acme.com/something"
        } elseif { [HTTP::uri] starts_with "/mail" } then {
            HTTP::redirect "https://usa.acme/webmail_exchange"
        } else {
            HTTP::redirect "https://mail.acme.com/webmail_zimbra"
        }   
    } 
}
