Duplicate Documents

in http://swish-e.org/current/docs/spider.html says to use

Digest::MD5 to fingerprint indexed pages and prevent indexing duplicates
pages

Do I *just* need to install the module for this to work? I'm not  clear on
this

thanks for any help. Thanks for pointing out the SSL support in the docs
too.
I can index https pages now.

thanks again
