URL encode iRule question

Hi all, I am trying to write iRule for to use URI::encode.

 

This is my request

 

1. HTTP Request > https://link.test.net/wstaion?name1=123xyz&rurl=rtrdce%rrere%fgfgf
2. Need to read the URL, if wstaion in the URL

3. generate url > https://link.test.net/loader.html?name1=123xyz&rurl=rtrdce%rrere%fgfgf >> set val final

    

4. rewrite to https://singon.test.net?sip=testred&furl=[URI::encode {$final}]

    

Note: name1= dynamic value; rurl = dynamic value

 

Thanks SP
