CURLOPT_FOLLOWLOCATION(3)				     curl_easy_setopt options					 CURLOPT_FOLLOWLOCATION(3)

NAME

       CURLOPT_FOLLOWLOCATION - follow HTTP 3xx redirects

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FOLLOWLOCATION, long enable);

DESCRIPTION

       A  long	parameter  set	to  1  tells  the  library  to follow any Location: header that the server sends as part of a HTTP header in a 3xx
       response. The Location: header can specify a relative or an absolute URL to follow.

       libcurl will issue another request for the new URL and follow new Location: headers all the way until no more such  headers  are  returned.
       CURLOPT_MAXREDIRS(3) can be used to limit the number of redirects libcurl will follow.

       libcurl	limits	what  protocols  it  automatically  follows to. The accepted protocols are set with CURLOPT_REDIR_PROTOCOLS(3). By default
       libcurl will allow all protocols on redirect except those disabled for security reasons: Since 7.19.4 FILE and SCP are disabled, and  since
       7.40.0 SMB and SMBS are also disabled.

       When  following	a  Location:,  the  3xx  response code that redirected it also dictates which request method it will use in the subsequent
       request: For 301, 302 and 303 responses libcurl will switch method to GET unless  CURLOPT_POSTREDIR(3)  instructs  libcurl  otherwise.  All
       other 3xx codes will make libcurl send the same method again.

       For  users  who think the existing location following is too naive, too simple or just lacks features, it is very easy to instead implement
       your own redirect follow logic with the use of curl_easy_getinfo(3)'s CURLINFO_REDIRECT_URL(3) option instead of using  CURLOPT_FOLLOWLOCA-
       TION(3).

DEFAULT

       0, disabled

PROTOCOLS

       HTTP(S)

EXAMPLE

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

	 /* example.com is redirected, so we tell libcurl to follow redirection */
	 curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

	 curl_easy_perform(curl);
       }

AVAILABILITY

       Along with HTTP

RETURN VALUE

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

NAME

       curl_easy_cleanup - End a libcurl easy handle

SYNOPSIS

       #include <curl/curl.h>

       void curl_easy_cleanup(CURL *handle);

DESCRIPTION

       This  function  must  be  the  last  function to call for an easy session. It is the opposite of the curl_easy_init(3) function and must be
       called with the same handle as input that a curl_easy_init(3) call returned.

       This might close all connections this handle has used and possibly has kept open until now - unless it was attached to a multi handle while
       doing  the  transfers.  Don't  call  this function if you intend to transfer more files, re-using handles is a key to good performance with
       libcurl.

       Occasionally you may get your progress callback or header callback called from within curl_easy_cleanup(3) (if previously set for the  han-
       dle  using  curl_easy_setopt(3)).  Like	if  libcurl decides to shut down the connection and the protocol is of a kind that requires a com-
       mand/response sequence before disconnect. Examples of such protocols are FTP, POP3 and IMAP.

       Any use of the handle after this function has been called and have returned, is illegal. curl_easy_cleanup(3) kills the handle and all mem-
       ory associated with it!

       For  libcurl versions before 7.17,: after you've called this function, you can safely remove all the strings you've previously told libcurl
       to use, as it won't use them anymore now.

RETURN VALUE

       None

EXAMPLE

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