The accepted +protocols are set with \fICURLOPT_REDIR_PROTOCOLS(3)\fP and it excludes the +FILE protocol by default. + +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 \fIcurl_easy_getinfo(3)\fP's +\fICURLINFO_REDIRECT_URL\fP option instead of using +\fICURLOPT_FOLLOWLOCATION(3)\fP. +.SH DEFAULT +0, disabled +.SH PROTOCOLS +HTTP(S) +.SH EXAMPLE +.nf +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); +} +.fi +.SH AVAILABILITY +Along with HTTP +.SH RETURN VALUE +Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR CURLOPT_REDIR_PROTOCOLS "(3), " CURLOPT_PROTOCOLS "(3), " +.BR CURLOPT_POSTREDIR "(3), " |
