Unread count is completely broken with this, so I'm keeping it in its own branch until I fix it. Also code is a mess.

Status Code 304: Not modified
|

By sending the `If-Modified-Since` header we get a proper status code, and no response.
|

This saves bandwidth for both the user and the servers and avoid unnecessary computation.
