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_FOLLOWLOCATION(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.
