-// Class that registers URL request throttler entries for URLs being accessed

-// throttler entries. It creates URL request throttler entries when new URLs
-// are registered, and does garbage collection from time to time in order to
-// clean out outdated entries. URL ID consists of lowercased scheme, host, port
-// and path. All URLs converted to the same ID will share the same entry.
