CURLOPT_COOKIEFILE(3)					     curl_easy_setopt options					     CURLOPT_COOKIEFILE(3)

NAME

       CURLOPT_COOKIEFILE - file name to read cookies from

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEFILE, char *filename);

DESCRIPTION

       Pass  a	pointer  to  a zero terminated string as parameter. It should point to the file name of your file holding cookie data to read. The
       cookie data can be in either the old Netscape / Mozilla cookie data format or just regular HTTP headers	(Set-Cookie  style)  dumped  to  a
       file.

       It also enables the cookie engine, making libcurl parse and send cookies on subsequent requests with this handle.

       Given  an  empty  or non-existing file or by passing the empty string ("") to this option, you can enable the cookie engine without reading
       any initial cookies.

       This option only reads cookies. To make libcurl write cookies to file, see CURLOPT_COOKIEJAR(3).

       Exercise caution if you are using this option and multiple transfers may occur.	If you use the	Set-Cookie  format  and  don't	specify  a
       domain  then  the  cookie  is  sent  for any domain (even after redirects are followed) and cannot be modified by a server-set cookie. If a
       server sets a cookie of the same name then both will be sent on a future transfer to that server, likely not what you intended.	To address
       these issues set a domain in Set-Cookie (doing that will include sub-domains) or use the Netscape format.

       If you use this option multiple times, you just add more files to read.	Subsequent files will add more cookies.

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

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.
