|Often you want to connect to a site to get data that
requires a name and password, but you want a simple
interface. For instance one that will work with
LWP::Simple. The following form of a URL is documented
but apparently not as widely known as it deserves to be.
It should work for all protocols.
A piece of trivia. Hotmail has an interesting use for
this. Their name/password form is submitted by https to
a script that does nothing but redirect to a URL with the
name and password inserted as above, that will require
Digest authentication. The browser without prompting then
uses the name and password (as originally typed in their
form) and from then on has http authentication loaded.
Turning form entries into http authentication securely
without encrypting your whole site is something that a lot
of people think is impossible. Well it is not, and that
is how you do it! :-)
