Prepared the iRule based on the hints provided in question. You can validate and let us know the result. 

when HTTP_REQUEST { 
      set url_http [HTTP::uri] 
 } 
 when HTTP_RESPONSE { 
    if { ([HTTP::status] == 404) && ( $url_http contains "url") } { 
              HTTP::respond 302 Location "http://191.168.10.20/xyz/"
    } 
 }

Hope it will work.
