Given the information that hosts are collected in a HashMap: Tomcat isn't sorting anything, and you can't sort a HashMap*. Hashing functions are designed to distribute a large key space over a much smaller set of "buckets" in constant time. The more apparently random the relationship between input and output, the better for this purpose, in most cases. The entries in a hashtable are deliberately DISordered on insertion. Hashing data is like hashing meat and potatoes: the result is expected to be finely divided and well mixed. ------------------- * You could sort its content into some other data structure, but apparently that's not done here. -- Mark H.
