tlslite.sessioncache module

Class for caching TLS sessions.

class tlslite.sessioncache.SessionCache(maxEntries=10000, maxAge=14400)

Bases: object

This class is used by the server to cache TLS sessions.

Caching sessions allows the client to use TLS session resumption and avoid the expense of a full handshake. To use this class, simply pass a SessionCache instance into the server handshake function.

This class is thread-safe.

__init__(maxEntries=10000, maxAge=14400)
