Detailed Description

Macro Definition Documentation

◆ REMOTE_DOUBLE_REV

#define REMOTE_DOUBLE_REV (3)

REMOTE_DOUBLE_REV will always force a DNS lookup, and also force a double reverse lookup, regardless of the HostnameLookups setting. The result is the (double reverse checked) hostname, or NULL if any of the lookups fail.

Definition at line 118 of file http_core.h.

◆ REMOTE_HOST

#define REMOTE_HOST (0)

REMOTE_HOST returns the hostname, or NULL if the hostname lookup fails. It will force a DNS lookup according to the HostnameLookups setting.

Definition at line 100 of file http_core.h.

◆ REMOTE_NAME

#define REMOTE_NAME (1)

REMOTE_NAME returns the hostname, or the dotted quad if the hostname lookup fails. It will force a DNS lookup according to the HostnameLookups setting.

Definition at line 106 of file http_core.h.

◆ REMOTE_NOLOOKUP

#define REMOTE_NOLOOKUP (2)

REMOTE_NOLOOKUP is like REMOTE_NAME except that a DNS lookup is never forced.

Definition at line 111 of file http_core.h.

◆ ap_get_remote_host()

const char * ap_get_remote_host	(	conn_rec *	conn,
		void *	dir_config,
		int	type,

	)

Lookup the remote client's DNS name or IP address

Parameters

conn	The current connection
dir_config	The directory config vector from the request
type	The type of lookup to perform. One of: REMOTE_HOST returns the hostname, or NULL if the hostname lookup fails. It will force a DNS lookup according to the HostnameLookups setting. REMOTE_NAME returns the hostname, or the dotted quad if the hostname lookup fails. It will force a DNS lookup according to the HostnameLookups setting. REMOTE_NOLOOKUP is like REMOTE_NAME except that a DNS lookup is never forced. REMOTE_DOUBLE_REV will always force a DNS lookup, and also force a double reverse lookup, regardless of the HostnameLookups setting. The result is the (double reverse checked) hostname, or NULL if any of the lookups fail.
str_is_ip	unless NULL is passed, this will be set to non-zero on output when an IP address string is returned

Returns: The remote hostname (based on the connection client_ip)

◆ ap_get_useragent_host()

const char * ap_get_useragent_host	(	request_rec *	req,
		int	type,
		int *	str_is_ip
	)

Lookup the remote user agent's DNS name or IP address

Parameters

req The current request

type

The type of lookup to perform. One of:

    REMOTE_HOST returns the hostname, or NULL if the hostname
                lookup fails.  It will force a DNS lookup according to the
                HostnameLookups setting.
    REMOTE_NAME returns the hostname, or the dotted quad if the
                hostname lookup fails.  It will force a DNS lookup according
                to the HostnameLookups setting.
    REMOTE_NOLOOKUP is like REMOTE_NAME except that a DNS lookup is
                    never forced.
    REMOTE_DOUBLE_REV will always force a DNS lookup, and also force
                  a double reverse lookup, regardless of the HostnameLookups

                  hostname, or NULL if any of the lookups fail.

str_is_ip unless NULL is passed, this will be set to non-zero on output when an IP address string is returned

Returns: The remote hostname (based on the request useragent_ip)
