To block some specific traffic from F5 for specific virtual directory

I never create iRule this is first time so please can you send me acctual iRule with below example:

 

 

Site: https://www.xyz.com/bac

 

Allowed below host:

 

174.26.53.0/24

 

172.56.36.2

 

175.63.54.0/24

 

Block: all others

 

 

Site: https://wwww.xyz.com

 

Allowed for any

 

 

So we require only filter for /bac virtual directory all other site running without any filter.
