CURLOPT_PROXY_SSLCERTTYPE - specify type of the proxy client SSL certificate

SYNOPSIS

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERTTYPE, char *type);

DESCRIPTION

Pass a pointer to a zero terminated string as parameter. The string should be the format of your client certificate used when connecting to a HTTPS proxy.

The application does not have to keep the string around after setting this option.
