title: Storing, Loading, and Updating a Trie in ASP.NET MVC 3
body: <p>I have a trie-based word detection algorithm for a custom dictionary. Note that regular expressions are too brittle with this dictionary as entries may contain spaces, periods, etc. </p>
  
  <p>I've implemented the algorithm in a local C# app that reads in the dictionary from file and stores the trie in memory (it's compact, so no RAM size issues at all). Now I would like to use this algorithm in an MVC 3 app on a cloud host like AppHarbor, with the added twist that I want a web interface to enable adding/editing words.</p>
  
  <p>It's fast enough that loading the dictionary from file and building the trie every time a user uploads their text would not be an issue (&lt; 1s on my laptop). However, if I want to enable admins to edit the dictionary via the web interface, that would seem tricky since the dictionary would potentially be getting updated while a user is trying to upload text for analysis.</p>
  
  <p>What is the best strategy for storing, loading, and updating the trie in an MVC 3 app?</p>
