+# NAME
+
+CURLOPT_PROXY_CAINFO - path to proxy Certificate Authority (CA) bundle
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAINFO, char *path);
+~~~
+
+# DESCRIPTION
+
+This option is for connecting to an HTTPS proxy, not an HTTPS server.
+
+Pass a char pointer to a null-terminated string naming a file holding one or
+more certificates to verify the HTTPS proxy with.
+
+If CURLOPT_PROXY_SSL_VERIFYPEER(3) is zero and you avoid verifying the
+server's certificate, CURLOPT_PROXY_CAINFO(3) need not even indicate an
+accessible file.
+
+This option is by default set to the system path where libcurl's CA
+certificate bundle is assumed to be stored, as established at build time.
+
+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 switches back to
+internal default.
+
+The default value for this can be figured out with CURLINFO_CAINFO(3).
+
+# DEFAULT
+
+Built-in system specific
+
+# %PROTOCOLS%
+
+# 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_CAINFO, "/etc/certs/cabundle.pem");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# NOTES
+
+For TLS backends that do not support certificate files, the
+CURLOPT_PROXY_CAINFO(3) option is ignored. Refer to
+https://curl.se/docs/ssl-compared.html
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
