HTTPS driver for LWP::UserAgent The LWP::Protocol::https module provide support for using HTTPS schemed URLs with LWP. LWP::Protocol::https is a plug-in to the LWP protocol handling, so you don't use it directly. Once the module is installed LWP is able to access sites using HTTP over SSL/TLS. If hostname verification is requested by LWP::UserAgent's ssl_opts, and neither SSL_ca_file nor SSL_ca_path is set, then SSL_ca_file is implied to be the one provided by ca-certificates. This module used to be bundled with the libwww-perl, but it was unbundled in v6.02 in order to be able to declare its dependencies properly for the CPAN tool-chain. Applications that need HTTPS support can just declare their dependency on LWP::Protocol::https and will no longer need to know what underlying modules to install.
