3.15 Can I do recursive fetches with curl?
There are three different kinds of "certificates" to keep track of when we
talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl.
- - Client certificate. The server you communicate may require that you can
- provide this in order to prove that you actually are who you claim to be.
- If the server doesn't require this, you don't need a client certificate.
-
- A client certificate is always used together with a private key, and the
- private key has a pass phrase that protects it.
-
- - Server certificate. The server you communicate with has a server
- certificate. You can and should verify this certificate to make sure that
- you are truly talking to the real server and not a server impersonating
- it.
-
- - Certificate Authority certificate ("CA cert"). You often have several CA
- certs in a CA cert bundle that can be used to verify a server certificate
- that was signed by one of the authorities in the bundle. curl does not
- come with a CA cert bundle but most curl installs provide one. You can
- also override the default.
-
- The server certificate verification process is made by using a Certificate
- Authority certificate ("CA cert") that was used to sign the server
- certificate. Server certificate verification is enabled by default in curl
- and libcurl and is often the reason for problems as explained in FAQ entry
- 4.12 and the SSLCERTS document
- (http://curl.haxx.se/docs/sslcerts.html). Server certificates that are
- "self-signed" or otherwise signed by a CA that you do not have a CA cert
- for, cannot be verified. If the verification during a connect fails, you
- are refused access. You then need to explicitly disable the verification

+
+ 4.20 curl doesn't return error for HTTP non-200 responses!
+
+ Correct. Unless you use -f (--fail).
+
+ When doing HTTP transfers, curl will perform exactly what you're asking it
+ to do and if successful it will not return an error. You can use curl to
+ test your web server's "file not found" page (that gets 404 back), you can
+ use it to check your authentication protected web pages (that get a 401
+ back) and so on.
+
+ The specific HTTP response code does not constitute a problem or error for
+ curl. It simply sends and delivers HTTP as you asked and if that worked,
+ everything is fine and dandy. The response code is generally providing more
+ higher level error information that curl doesn't care about. The error was
+ not in the HTTP transfer.
+
+ If you want your command line to treat error codes in the 400 and up range
+ as errors and thus return a non-zero value and possibly show an error
+ message, curl has a dedicated option for that: -f (CURLOPT_FAILONERROR in
+ libcurl speak).
+
+ You can also use the -w option and the variable %{response_code} to extract
+ the exact response code that was return in the response.
+
+ 4.21 Why is there a HTTP/1.1 in my HTTP/2 request?
+
+ If you use verbose to see the HTTP request when you send off a HTTP/2
+ request, it will still say 1.1.
+
+ The reason for this is that we first generate the request to send using the
+ old 1.1 style and show that request in the verbose output, and then we
+ convert it over to the binary header-compressed HTTP/2 style. The actual
+ "1.1" part from that request is then not actually used in the transfer. The
+ binary HTTP/2 headers are not human readable.
