I understand a bit about digest authentication from here http://en.wikipedia.org/wiki/Digest_access_authentication, but I am pretty unclear on where, when or how it is used. I can't find anything on that side of it.
Where, when and why would a webmaster use it? Does it require any extra code on a site if the server has it implemented?
As you can see, I pretty much in the dark about how it is used, so any info would be helpful.
Maybe this could become a FAQ
