                     27: .SH SYNOPSIS
                     28: #include <curl/curl.h>
                     29: 
                     30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYSTATUS, long verify);
                     31: .SH DESCRIPTION
                     32: Pass a long as parameter set to 1 to enable or 0 to disable.
                     33: 
                     34: This option determines whether libcurl verifies the status of the server cert
                     35: using the "Certificate Status Request" TLS extension (aka. OCSP stapling).
                     36: 
                     37: Note that if this option is enabled but the server does not support the TLS
                     38: extension, the verification will fail.
                     39: .SH DEFAULT
                     40: 0
                     41: .SH PROTOCOLS
