CURLOPT_REFERER(3)					     curl_easy_setopt options						CURLOPT_REFERER(3)

NAME

       CURLOPT_REFERER - set the HTTP referer header

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REFERER, char *where);

DESCRIPTION

       Pass  a pointer to a zero terminated string as parameter. It will be used to set the Referer: header in the http request sent to the remote
       server. This can be used to fool servers or scripts. You can also set any custom header with CURLOPT_HTTPHEADER(3).

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* tell it where we found the link to this place */
	 curl_easy_setopt(curl, CURLOPT_REFERER, "http://example.com/aboutme.html");

	 curl_easy_perform(curl);
       }

AVAILABILITY

       If built with HTTP support

RETURN VALUE

       Returns CURLE_OK if HTTP support is enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.

CURLOPT_MAXREDIRS(3)					     curl_easy_setopt options					      CURLOPT_MAXREDIRS(3)

NAME

       CURLOPT_MAXREDIRS - maximum number of redirects allowed

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXREDIRS, long amount);

DESCRIPTION

       Pass  a	long.  The  set  number will be the redirection limit amount. If that many redirections have been followed, the next redirect will
       cause an error (CURLE_TOO_MANY_REDIRECTS). This option only makes sense if the CURLOPT_FOLLOWLOCATION(3) is used at the same time.

       Setting the limit to 0 will make libcurl refuse any redirect.

       Set it to -1 for an infinite number of redirects.

DEFAULT

       -1, unlimited

PROTOCOLS

       HTTP(S)

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/");

	 /* enable redirect following */
	 curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

	 /* allow three redirects */
	 curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 3L);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       Along with HTTP

RETURN VALUE

       Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
