Starting a Server

• A port to listen on. The server will actually listen on a series of ports (for different kinds of connections) starting with the port given in the constructor. (This will likely change in a future release to allow explicit assignment of ports for each protocol.)
• The name (path) of a directory to store persistent copies of objects in. This directory will be created if it does not exist.
• The depth of the storage directory structure. The file-based storage mechanism will hash objects across multiple directories based on this parameter. The hashing uses (decimal) digits taken from CORK ObjectIDs. If this value is 0, all objects will be put into a single directory. If it is 1, objects will be hashed by type, with one directory per object class. If it is greater than 1, objects of each type will be hashed across up to 10^(depth - 1) directories. Except for testing purposes, this parameter should be 2 or greater.
• A boolean flag indicating whether or not HTTP connections should be supported. HTTP support is still somewhat experimental, so you may choose to turn it off if you do not need it.
• An integer indicating how often (in seconds) idle objects in the server's in-memory cache should be purged.
