need to optimize search block

In my iRule, i have below block. Can someone please optimize this code. My concern is that "static::payld" may store few 100 URLs, and iterating over these URLs will impact the performance.

 

 

foreach pl_uri $static::payld {

 

if { ([HTTP::uri] starts_with $pl_uri) and not( $pl_uri equals "" ) } {

 

log local0. "Redirect: For [HTTP::uri] matched $pl_uri"

 

set redirect 1

 

break

 

}

 

}

    Found out that we can use matchclass method on lists too... pretty cool. above code is replaced as

     

     

    set static::payld [lreplace $static::payld [lsearch -exact $static::payld ""] [lsearch -exact $static::payld ""]]

     

    if { [matchclass [HTTP::uri] starts_with $static::payld] } {

     

    HTTP::respond 302 Location $kill_switch_url

     

    }
