The LWP::Protocol::http10 module provide support for using HTTP/1.0 protocol with LWP. To use it you need to call LWP::Protocol::implementor() to override the standard handler for http URLs. This module used to be bundled with the libwww-perl, but it was unbundled in v6.02 as part of the general cleanup for the 6-series. LWP::Protocol::http10 is deprecated.
