NAME

       CURLOPT_RESOLVE - provide custom host name to IP address resolves

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESOLVE,
				 struct curl_slist *hosts);

DESCRIPTION

       Pass  a pointer to a linked list of strings with host name resolve information to use for requests with this handle. The linked list should
       be  a  fully  valid  list  of  struct  curl_slist  structs  properly  filled  in.  Use  curl_slist_append(3)  to  create   the	list   and
       curl_slist_free_all(3) to clean up an entire list.

       Each  single  name  resolve string should be written using the format HOST:PORT:ADDRESS where HOST is the name libcurl will try to resolve,
       PORT is the port number of the service where libcurl wants to connect to the HOST and ADDRESS is the numerical IP address.  If  libcurl	is
       built to support IPv6, ADDRESS can of course be either IPv4 or IPv6 style addressing.

       This option effectively pre-populates the DNS cache with entries for the host+port pair so redirects and everything that operations against
       the HOST+PORT will instead use your provided ADDRESS. Addresses set with CURLOPT_RESOLVE(3) will not time-out from the DNS cache like ordi-
       nary entries.

       The provided ADDRESS set by this option will be used even if CURLOPT_IPRESOLVE(3) is set to make libcurl use another IP version.

       Remove names from the DNS cache again, to stop providing these fake resolves, by including a string in the linked list that uses the format
       "-HOST:PORT". The host name must be prefixed with a dash, and the host name and port number must exactly match what was already added  pre-
       viously.

DEFAULT

       NULL

PROTOCOLS

       All

EXAMPLE

       CURL *curl;
       struct curl_slist *host = NULL;
       host = curl_slist_append(NULL, "example.com:80:127.0.0.1");

       curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_RESOLVE, host);
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 curl_easy_perform(curl);

	 /* always cleanup */
	 curl_easy_cleanup(curl);
       }

       curl_slist_free_all(host);

AVAILABILITY

       Added in 7.21.3. Removal support added in 7.42.0.

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
