Hostname uri and source-ip based access

That's close in concept. If you want to check the hostname and URI, you'll need to wait until the HTTP_REQUEST event to check as this is when the HTTP headers have been parsed. The URI will always start with a forward slash, so you might want to see if the URI equals "/mcx".

Also, there is a default datagroup named private_net which you can reference with matchclass:

 
 class private_net { 
    network 10.0.0.0/8 
    network 172.16.0.0/12 
    network 192.168.0.0/16 
 } 
 

So you could use something like this:

 
 when HTTP_REQUEST { 
  
     Check if client IP is a private network 
    if {[matchclass [IP::client_addr] equals $::private_net]}{ 
  
        Check if requested host is hostname.com 
       if {[string tolower [HTTP::host]] eq "hostname.com"}{ 
  
           Check if URI starts with "/mcx" 
          if {[string tolower [HTTP::uri]] starts_with "/mcx"}{ 
  
             HTTP::redirect "http://hostname.com/public" 
          } 
       } 
    } 
 }
