2 http request rules merge to one - one referer the other set access only

Thanks for the reply guys and they got me wondering if i was doing the best way.

Now going to accept all except the part of the url i dont want to give access and use cookies as the allowed access.

So have decided to go with two other rules instead and will merge these together.

Is this a better way to go?

when HTTP_REQUEST {

    Check for referer
    if { ([HTTP::header Referer] starts_with "http://allowsite.com") } {
        log local0. "Our referer is - [URI::host [HTTP::header Referer]]"

            Check for cookie
            if { not ( [HTTP::cookie value ACCESS-AUTHORIZED] contains "Go1234") } {                   
            log local0. "Does a cookie exist? [HTTP::cookie exists IMHERE-COOKIE] ...Lets set a cookie"
            set ckname " ACCESS-AUTHORIZED "
            set ckvalue "Go1234"
            set cookie [format "%s=%s; path=/; domain=%s" $ckname $ckvalue "mysite.com.au"]
            set cookie [format "%s=%s; path=/; expires=[clock format [expr {[clock seconds]+300}] -format "%a, %d %h %Y %T GMT" -gmt true]; domain=%s" $ckname $ckvalue "mysite.com.au"]
            HTTP::respond 302 Location "https://mysite.com.au/ /correctlocation" "Set-Cookie" $cookie
                } else {
                log local0. "Cookie already exists"
                pool POOL_TheCorrectPool-80
            }
    } elseif { ( [HTTP::cookie value ACCESS-AUTHORIZED] contains "Go1234") } {  
        log local0. "We already have a cookie..."
        pool POOL_TheCorrectPool-80
        } else {
        log local0. "No Cookie...whoops"
        HTTP::redirect "https://notauthorized.com/"
                }
    }

2nd rule

when HTTP_REQUEST { 
    log local0. "uri is [HTTP::uri]" 
    switch -glob -- [string tolower [HTTP::uri]] {
        "*admin*" {
            HTTP::respond 200 content { The URL you requested is incorrect. For other information, please contact IT Administrator @ 999999 }
            log local0. "Request from [IP::client_addr] for [HTTP::uri] has been rejected." 
        }
    }        
}
