Converting iRule from v9 to v12

In the process of migrating from v9.4.7 to v12.1.1 and am having issues with iRules... In the following I am pulling string Data Groups for B2B_Blocked_URLS and B2B_URLS... Could you assist on how I would do this on the new version?

when RULE_INIT {
    set ::DEFAULT_URI "/b2b/init.do"
}
when HTTP_REQUEST {
    if { [matchclass [HTTP::uri] contains $::B2B_Blocked_URLS] } {
        HTTP::redirect "$::DEFAULT_URI" 
    } 
    if { [matchclass [HTTP::uri] contains $::B2B_URLS] } { 
    } else { 
        log local0.crit [HTTP::uri] HTTP::redirect "$::DEFAULT_URI"
    }
}

    Hi Jim,

    You can try the following, please be advised you can now achieve the same results using a Traffic Policy (configured in the GUI). Code that is no longer supported are variables declared in the global namespace ($::var) these will demote your CMP so the iRule will only run on one CPU. Also matchclass has been deprecated

     

    when RULE_INIT {
    set static::DEFAULT_URI "/b2b/init.do"
}

when HTTP_REQUEST {

    if {[class match [HTTP::uri] contains B2B_Blocked_URLS] } {
        HTTP::redirect $static::DEFAULT_URI 
    } elseif { not ([class match [HTTP::uri] contains B2B_URLS]) } {
        log local0.crit [HTTP::uri]
        HTTP::redirect $static::DEFAULT_URI
    }
}
