Daniel Gustafsson 8d67c61c47 curldown: Fix email address in Copyright
The curldown conversion accidentally replaced daniel@haxx.se with
just daniel.se.  This reverts back to the proper email address in
the curldown docs as well as in a few other stray places where it
was incorrect (while unrelated to curldown).

NAME

CURLOPT_SSL_VERIFYSTATUS - verify the certificate's status

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_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 server cert using the "Certificate Status Request" TLS extension (aka. OCSP stapling).

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

DEFAULT

0

PROTOCOLS

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    /* ask for OCSP stapling! */
    curl_easy_setopt(curl, CURLOPT_SSL_VERIFYSTATUS, 1L);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.41.0. This option is currently only supported by the OpenSSL and GnuTLS TLS backends.

RETURN VALUE

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