示例1: OpenDb
/**
* Lookup up a key in the database is a two step process:
*
* a) First we look for any Entries in the database that might apply to this
* url. For each URL there are one or two possible domain names to check:
* the two-part domain name (example.com) and the three-part name
* (www.example.com). We check the database for both of these.
* b) If we find any entries, we check the list of fragments for that entry
* against the possible subfragments of the URL as described in the
* "Simplified Regular Expression Lookup" section of the protocol doc.
