  Should we do Automatic File Suffix Binding?
.

By default, libwww uses the file suffix bindings
to figure out the media type, natural language, charset, content encoding,
etc and assign the values to the anchor of the local file.

However, in some situations, the application can either already have done
this or isn't interested in using the libwww bindings. You can control whether
libwww should do thi or not using the following methods:
