CURLOPT_DOH_SSL_VERIFYSTATUS(3)                       curl_easy_setopt options

NAME
       CURLOPT_DOH_SSL_VERIFYSTATUS - verify the DOH SSL certificate's status

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_SSL_VERIFYSTATUS,
       long verify);

DESCRIPTION
       Pass a long as parameter set to 1 to enable or 0 to disable.

       This option determines whether libcurl verifies the status of the DOH
       (DNS-over-HTTPS) server cert using the "Certificate Status Request" TLS
       extension (aka. OCSP stapling).

       This option is the DOH equivalent of _SSL_VERIFYSTATUS&section=3">CURLOPT_SSL_VERIFYSTATUS(3) and
       only affects requests to the DOH server.

       Note that if this option is enabled but the server does not support the
       TLS extension, the verification will fail.

DEFAULT
       0

PROTOCOLS
       DOH

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         curl_easy_setopt(curl, CURLOPT_DOH_URL, "https://cloudflare-dns.com/dns-query");

         /* Ask for OCSP stapling when verifying the DOH server */
         curl_easy_setopt(curl, CURLOPT_DOH_SSL_VERIFYSTATUS, 1L);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.76.0. This option is currently only supported by the
       OpenSSL, GnuTLS and NSS TLS backends.

RETURN VALUE
       Returns CURLE_OK if OCSP stapling is supported by the SSL backend,
       otherwise returns CURLE_NOT_BUILT_IN.
