# Class Http_client_conncache.aggressive_cache

    class aggressive_cache : unit -> connection_cache

This type of cache tries to keep connections as long open as possible. The consequence is that users are responsible for closing the descriptors (by calling `close_connection_cache`) when the cache is no longer in use. It is also possible to derive a special version of the cache from this class, e.g. for closing descriptors when they are idle for some time.
