(HTTP) Sends the “Referrer Page” information to the HTTP server. When used with -L, –location you can append “;auto” to the -e, –referer URL to make curl automatically set the previous URL when it follows a Location: header. The “;auto” string can be used alone, even if you don’t set an initial -e, –referer. This can also be set with the -H, –header flag of course.
So early failures will be “hidden” by subsequent successful transfers. When curl is used to do multiple transfers on the command line, it will attempt to operate on each given URL, one by one. By default, it will ignore errors if there are more URLs given and the last URL’s success will determine the error code curl returns.
At present only IMAP, POP3 and SMTP support login options. For more information about the login options please see RFC 2384, RFC 5092 and IETF draft draft-earhart-url-smtp-00. You can use the login options to specify protocol specific options that may be used during authentication.
This option changes the default action for all given URLs to be dealt with as if -O, –remote-name were used for each one. So if you want to disable that for a specific URL after –remote-name-all has been used, you must use “-o -” or –no-remote-name.
At a specific cluster node in a cluster of servers. This option is suitable to direct requests at a specific server, e. For a request to the given HOST1:PORT1 pair, connect to HOST2:PORT2 instead. “HOST2” and “PORT2” may also be the empty string, meaning “use the request’s original host/port”. “HOST1” and “PORT1” may be the empty string, meaning “any host/port”. It does NOT affect the hostname/port that is used for TLS/SSL (e. This option is only used to establish the network connection. SNI, certificate verification) or for the application protocols.
EPRT and LPRT are extensions to the original FTP protocol, and may not work on all servers, but they enable more functionality in a better way than the traditional PORT command. Curl will normally always first attempt to use EPRT, then LPRT before using PORT, but with this option, it will use PORT right away. (FTP) Tell curl to disable the use of the EPRT and LPRT commands when doing active FTP transfers.
(HTTP) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response code), this option will make curl redo the request on the new place. If used together with -i, –include or -I, –head, headers from all requested pages will be shown. You can limit the amount of redirects to follow by using the –max-redirs option. If a redirect takes curl to a different host, it won’t be able to intercept the user+password. When authentication is used, curl only sends its credentials to the initial host. See also –location-trusted on how to change this.
Python’s requests module will fail with an error when you try to use it with SSL. After importing you can delete the certificate file that you saved.
The VPN server can examine a X. Since the device cannot be duplicated and requires a valid password, the server is able to authenticate the user with a high degree of confidence. Cryptographic devices are commonly called “smart cards” or “tokens”, and are used in conjunction with a PKI (Public Key Infrastructure). 509 certificate and verify that the user holds the corresponding private secret key.
Why the redundant route and iroute statements, you might ask. The reason is that route controls the routing from the kernel to the OpenVPN server (via the TUN interface) while iroute controls the routing from the OpenVPN server to the remote clients.
Defining a part’s data from a named non-regular file (such as a named pipe or similar) is unfortunately not subject to buffering and will be effectively read at transmission time; since the full size is unknown before the transfer starts, data is sent as chunks by HTTP and rejected by IMAP. This goes for both @ and < constructs. To read content from stdin instead of a file, use – as the filename. If stdin is not attached to a regular file, it is buffered first to determine its size and allow a possible resend.
To just get the content part from a file, prefix the file name with the symbol
