Try this out: 

  
  when HTTP_REQUEST {   
  set persistTo [session lookup \ 
 source_addr [IP::client_addr]]  
  set default_pool [LB::server pool]   
  set timeOut 3600  
    
  switch [ findstr [string tolower \ 
 [HTTP::uri]] "node=" 5 2] {  
  01 { set persistTo 192.168.49.97 }  
  02 { set persistTo 192.168.49.98 }  
  03 { set persistTo 192.168.49.99 }  
  }  
    
  if {$persistTo eq ""} {  
  pool $default_pool   
  } else {  
  pool $default_pool member $persistTo  
  session add source_addr [IP::client_addr] \ 
 $persistTo $timeOut  
  }  
    
  }

Hope it helps.
