New to iRules: Need persistance based on virutal directory

OK, here is what I've come up with so far but I need some more help.

 
  rule sautooffice_uri {  
       when HTTP_REQUEST {  
          if { [HTTP::uri] starts_with "/sautooffice" } {  
     persist cookie insert cdmao  
     pool www.cdmdata.com  
          }  
       }  
    
  virtual CDMDataProduction {  
     destination 10.250.110.100:http  
     ip protocol tcp  
     profile http tcp  
     pool www.cdmdata.com  
      persist AppCookie  
     rule sautooffice_uri  
  } 
 

If I am reading this correctly it will persist all of the connections going to the pool CDMDataProduction. I need to only persist those that have the uri /sauotooffice. How do I NOT persist any other sessions that do NOT use /sautooffice?

Thanks,

Tim
