+# NAME
+
+CURLOPT_PROXY_CAPATH - directory holding HTTPS proxy CA certificates
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath);
+~~~
+
+# DESCRIPTION
+
+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.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again and switch back to
+internal default.
+
+The default value for this can be figured out with CURLINFO_CAPATH(3).
+
+# DEFAULT
+
+NULL

+# EXAMPLE
+
+~~~c
+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);
+  }
+}
