CURLOPT_PROXY_CAPATH3
Directory holding https proxy ca certificates
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath);
Overview
Pass a char pointer to a null-terminated string naming a directory holding multiple CA certificates to verify the HTTPS proxy with. If libcurl is built against OpenSSL, the certificate directory must be prepared using the OpenSSL c_rehash utility. This makes sense only when CURLOPT_PROXY_SSL_VERIFYPEER(3) is enabled (which it is by default).
The application does not have to keep the string around after setting this option.
The default value for this can be figured out with CURLINFO_CAPATH(3).
Default
NULL
Protocols
Everything used over an HTTPS proxy
Examples
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* using an HTTPS proxy */
curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:443");
curl_easy_setopt(curl, CURLOPT_PROXY_CAPATH, "/etc/cert-dir");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
Return value
CURLE_OK if supported; or an error such as:
CURLE_NOT_BUILT_IN - Not supported by the SSL backend
CURLE_UNKNOWN_OPTION
CURLE_OUT_OF_MEMORY
