Hi guys,
I'm trying to store some variables into the SSL session cache, but i can't seems to pinpoint when/where the SSL session cache is generated.
I think I was able to store the data into the cache, but when i pull the value out, they are different...
I've added this custom struct in the ssl_private.h:
| Code: |
typedef struct test_data_st {
int a;
int b;
} TEST_SESSION_DATA;
static int test_sess_data_idx = -1;
|
I'm not entirely sure where to save the data yet, but currently I'm doing it in the ssl_hook_Fixup:
| Code: |
if (test_sess_data_idx == -1)
{
test_sess_data_idx = SSL_SESSION_get_ex_new_index(0, "MY DATA", NULL, NULL, NULL);
}
SSL_SESSION *sess = (SSL_session_reused(ssl) ? SSL_get_session(ssl) : NULL);
if (sess)
{
TEST_SESSION_DATA * td = NULL;
td = (TEST_SESSION_DATA *) SSL_SESSION_get_ex_data(sess, test_sess_data_idx);
int valid = 0;
if (td == 0)
{
TEST_SESSION_DATA d;
d.a = 1;
d.b = 1;
SSL_SESSION_set_ex_data(sess, test_sess_data_idx, &d);
}
}
else
{
ap_log_rerror(APLOG_MARK, APLOG_INFO, 0, r, "a: %d", td->a);
ap_log_rerror(APLOG_MARK, APLOG_INFO, 0, r, "b: %d", td->b);
}

The values I'm getting back are like:

Anyone know at which step is the SSL session cache created?

| The SSL sessions are not cached unless you have installed and configured a session caching module such as mod_socahce_memcache. Then depending on the type of caching module the location of the cahce will differ and it can be a file, a memory location or an external store. |
