Checking for file from iRule?

Using the suggestions posted in reply to my posts, here is what I have come up with so far:

 
 when HTTP_REQUEST {  
   if { [PROFILE::exists serverssl] == 1 } {  
     set downtimepool "Downtime-SSL"  
     set downtimemember "10.21.67.103"  
     set downtimeport "16443"  
     log local0. "Virtual server has SSL server profile"  
   } else {  
   set downtimepool "Downtime-NonSSL"  
   set downtimemember "10.21.67.103"  
   set downtimeport "16080"  
   log local0. "Virtual server has no SSL server profile"  
   }  
   if { ([LB::status pool $downtimepool member $downtimemember $downtimeport] eq "up") and (![IP::addr [IP::client_addr]/16 equals 10.21.0.0]) } {  
     pool $::downtimepool  
     log local0. "Sending request to pool $downtimepool"  
   }  
 } 
 

Now I am running into a problem with PROFILE::exists serverssl, testing it for one server has serverssl set, the above rule still enters the else {} instead.
