Re: double posting comments on weblogs

In this post, the basic message is, "Provide a mechanism to detect duplicate comments so that duplicate comments are not added to the blog." We do this in blojsom by taking an MD5 of the author and comment text. This gives us our internal comment ID. If the comment "ID" exists, we don't write the comment. This also applies to our processing of trackbacks as well to prevent duplicate trackback submission.
