# Max Entries in POST Data Preservation Storage

When [POST Data Preservation in Files or Cache](org.forgerock.agents.pdp.use.filesystem.enabled.html) is `false`, the maximum number of entries in the POST data preservation storage cache.

When [POST Data Preservation in Files or Cache](org.forgerock.agents.pdp.use.filesystem.enabled.html) is `true`, the maximum number of files in the [POST Data Preservation File Directory](org.forgerock.agents.pdp.directory.html).

When the maximum is reached, old entries are discarded.

Use this property to mitigate the risk of DoS attacks.

[POST Data Preservation Storage Size](org.forgerock.agents.pdp.cache.total.size.mb.html) takes precedence over this property.
