| 54 | .Sh NAME | ||
| 55 | .Nm SSL_CTX_flush_sessions | ||
| 56 | .Nd remove expired sessions | ||
| 57 | .Sh SYNOPSIS | ||
| 58 | .In openssl/ssl.h | ||
| 59 | .Ft void | ||
| 60 | .Fn SSL_CTX_flush_sessions "SSL_CTX *ctx" "long tm" | ||
| 61 | .Sh DESCRIPTION | ||
| 62 | .Fn SSL_CTX_flush_sessions | ||
| 63 | causes a run through the session cache of | ||
| 64 | .Fa ctx | ||
| 65 | to remove sessions expired at time | ||
| 66 | .Fa tm . | ||
| 67 | .Pp | ||
| 68 | If enabled, the internal session cache will collect all sessions established | ||
| 69 | up to the specified maximum number (see | ||
| 70 | .Xr SSL_CTX_sess_set_cache_size 3 ) . | ||
| 71 | As sessions will not be reused once they are expired, they should be | ||
| 72 | removed from the cache to save resources. | ||
| 73 | This can either be done automatically whenever 255 new sessions were | ||
| 74 | established (see | ||
| 75 | .Xr SSL_CTX_set_session_cache_mode 3 ) | ||
| 76 | or manually by calling | ||
| 77 | .Fn SSL_CTX_flush_sessions . | ||
| 78 | .Pp | ||
| 79 | The parameter | ||
| 80 | .Fa tm | ||
| 81 | specifies the time which should be used for the | ||
| 82 | expiration test, in most cases the actual time given by | ||
| 83 | .Fn time 0 | ||
| 84 | will be used. | ||
| 85 | .Pp | ||
| 86 | .Fn SSL_CTX_flush_sessions | ||
| 87 | will only check sessions stored in the internal cache. | ||
| 88 | When a session is found and removed, the | ||
| 89 | .Va remove_session_cb | ||
| 90 | is however called to synchronize with the external cache (see | ||
| 91 | .Xr SSL_CTX_sess_set_get_cb 3 ) . | ||
