module Nethttp_client_conncache:sig..end
Connection cache
This module allows one to create special connection caches, e.g. by deriving from the official ones

typeconn_state =[ `Active of < > | `Inactive of inactive_data ]
A TCP connection may be either `Inactive, i.e. it is not used
by any pipeline, or `Active obj, i.e. it is in use by the pipeline
obj (this is the Nethttp_client.pipeline coerced to < >).
Since Ocamlnet-4, `Inactive connections carry an inactive_data
record (was a transport_layer_id before).
Since Ocamlnet-3.3, `Inactive connections carry the transport
ID as argument. Since 3.8, there is the option of storing an exception
value private_data. This may be used by implementations to store
private data together with the file descriptor.

class restrictive_cache :unit ->connection_cache
A restrictive cache closes connections as soon as there are no pending requests.
class aggressive_cache :unit ->connection_cache
This type of cache tries to keep connections as long open as possible.
