The third argument of ap_register_provider and ap_lookup_provider is
provider_version.
Most modules use hardcoded "0" as provider_version, but is it correct way?
I think mod_socache_* approach is right.
* include/ap_socache.h line 167:
/** The provider group used to register socache providers. */
#define AP_SOCACHE_PROVIDER_GROUP "socache"
/** The provider version used to register socache providers. */
#define AP_SOCACHE_PROVIDER_VERSION "0"
* modules/cache/mod_socache_shmcb.c line 868:
static void register_hooks(apr_pool_t *p)
{
ap_register_provider(p, AP_SOCACHE_PROVIDER_GROUP, "shmcb",
AP_SOCACHE_PROVIDER_VERSION,
&socache_shmcb);
