-A long parameter set to 1 tells the library to follow any Location: header
-that the server sends as part of an HTTP header in a 3xx response. The
-Location: header can specify a relative or an absolute URL to follow.
+The long parameter \fIenable\fP set to 1 tells the library to follow any
+Location: header that the server sends as part of an HTTP header in a 3xx
+response. The Location: header can specify a relative or an absolute URL to
+follow.
+
+\fIenable\fP is a bitmask. If you set the \fICURLFOLLOW_NO_CUSTOMMETHOD\fP
+bit, it will tell libcurl that the method set with
+\fICURLOPT_CUSTOMREQUEST(3)\fP will not be used after a redirect if the HTTP
+response says so.
libcurl will issue another request for the new URL and follow new Location:
headers all the way until no more such headers are returned.
