0x0–0xFFFFFFFF (certificates) |
0x35 (53) |
Description
Specifies the maximum number of certificates stored in the certificate cache, which stores information about certificates found in incoming messages. This cache helps Message Queuing (also known as MSMQ) authenticate incoming messages more quickly.
If the cache is full (that is, if the number of certificates equals the value of the CertInfoCacheSize entry) when the next certificate arrives, then Message Queuing deletes half of the certificates in the cache. The oldest certificates are deleted first.
This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
Note
- Entries in the certificate cache are not subject to an expiration time. Certificates are deleted from the cache only when the cache is full.
