31 Pass a long set to 2L as asking curl to \fIverify\fP in the HTTPS proxy's
32 certificate name fields against the proxy name.
34 This option determines whether libcurl verifies that the proxy cert contains
35 the correct name for the name it is known as.
37 When \fICURLOPT_PROXY_SSL_VERIFYHOST(3)\fP is 2, the proxy certificate must
38 indicate that the server is the proxy to which you meant to connect to, or the
41 Curl considers the proxy the intended one when the Common Name field or a
42 Subject Alternate Name field in the certificate matches the host name in the
43 proxy string which you told curl to use.
45 When the \fIverify\fP value is 1L, \fIcurl_easy_setopt\fP will return an error
46 and the option value will not be changed due to old legacy reasons.
48 When the \fIverify\fP value is 0L, the connection succeeds regardless of the
49 names used in the certificate. Use that ability with caution!
51 See also \fICURLOPT_PROXY_SSL_VERIFYPEER(3)\fP to verify the digital signature
52 of the proxy certificate. If libcurl is built against NSS and
53 \fICURLOPT_PROXY_SSL_VERIFYPEER(3)\fP is zero,
54 \fICURLOPT_PROXY_SSL_VERIFYHOST(3)\fP is also set to zero and cannot be

67 curl_easy_setopt(curl, CURLOPT_PROXY_SSL_VERIFYHOST, 2L);
69 curl_easy_perform(curl);
77 Returns CURLE_OK if TLS is supported, and CURLE_UNKNOWN_OPTION if not.
79 If 1 is set as argument, \fICURLE_BAD_FUNCTION_ARGUMENT\fP is returned.
