@ -1883,12 +1883,18 @@ something, you don't actually change how libcurl behaves or acts in regards
to the particular request method, it will only change the actual string sent
in the request.
For example: if you tell libcurl to do a HEAD request, but then change the
request to a "GET" with \fBCURLOPT_CUSTOMREQUEST\fP you'll still see libcurl
act as if it sent a HEAD even when it does send a GET.
For example:
To switch to a proper HEAD, use \fICURLOPT_NOBODY\fP, to switch to a proper
POST, use \fICURLOPT_POST\fP or \fICURLOPT_POSTFIELDS\fP and so on.
With the HTTP protocol when you tell libcurl to do a HEAD request, but then
specify a GET though a custom request libcurl will still act as if it sent a
HEAD. To switch to a proper HEAD use \fICURLOPT_NOBODY\fP, to switch to a
proper POST use \fICURLOPT_POST\fP or \fICURLOPT_POSTFIELDS\fP and to switch
to a proper GET use CURLOPT_HTTPGET.
With the POP3 protocol when you tell libcurl to use a custom request it will
behave like a LIST or RETR command was sent where it expects data to be
returned by the server. As such \fICURLOPT_NOBODY\fP should be used when
specifing commands such as DELE and NOOP for example.
Restore to the internal default by setting this to NULL.
