Considering +these are efficient string-based search trees, this gave me the idea to use it +as the backend for a URL shortener! + +This implementation currently uses a ternary trie as its search tree. The +persistence model is very simple; I simply append a line to a text file every +time a URL is added, and add the lines of this file to the trie on startup. The +trie is stored completely im memory, and no I/O operations are required when +requesting a redirect.
