great work Alexey! Guys, I have few questions regarding the algorithm:

1. When file is found in the cache(path match only), do we also need to check the size and modification time to be sure the file data is up to date?
2. The cache will always be queried for new files? even after initialization phase?
3. Let's concider to make the path cache concept as part of ContentData. Then you will only need to query ContentData if path exists.
