Detailed Description

An entry in the hostname hash table cache.

Host name cache does two things:

• caches host names to save DNS look ups;
• counts errors from IP.

Host name can be empty (that means DNS look up failed), but errors still are counted.

char Host_entry::ip_key[HOST_ENTRY_KEY_SIZE]

Client IP address. This is the key used with the hash table.

The client IP address is always expressed in IPv6, even when the network IPv6 stack is not present.

This IP address is never used to connect to a socket.

Host_errors Host_entry::m_errors

Error statistics.

Definition at line 154 of file hostname.h.

bool Host_entry::m_host_validated

The hostname is validated and used for authorization.

Definition at line 148 of file hostname.h.

char Host_entry::m_hostname[HOSTNAME_LENGTH+1]

One of the host names for the IP address. May be a zero length string.

Definition at line 144 of file hostname.h.
