Commenting a comment, will create wp-cache and meta-wp-cache files

    I do not use any cookies, but I usually find there exist a lot of wp-cache files (not supercache). I have debugged and found out there are created when someone (typically a spambot) is replying to a comment (not creating a new one) as a non logged user.
    This will trigger something in WP or WP-Supercache that will create a new wp-cache and new meta-wp-cache (and a new supercache) every time the bot interact with the same page. And they typically hammer the page.
    I’ve reproduced this manually and the same happens in a browser. No cookies are set so I don’t understand why these files are created.

    I’m not able to find out the bug myself, and if this is not a bug, please consider and option to do not create these files when comments are made by not logged users.

    As a side note I have the option to “Only refresh current page when comments made”

    Normally a cookie is set when someone leaves a comment. Spam bots should ignore those cookies and they don’t need to load the page again. They simply POST the spam comment to the page blindly.

    Have you tried the debug log to see this “post a spam comment, load the page after” action?

    It’s not a bug. There is a cookie being set in the browsers of your site visitors.

    If you really want to ignore cookies then check “Make known users anonymous so they’re served supercached static files” in the advanced settings page.

    I had “Make known users anonymous so they’re served supercached static files” options already set.
    I’m not sure how the bot is engineered, maybe it’s a browser. And it’s hammering multiple time at a second.

    I can’t see a cooke set in my browser when I reply to a comment.

    I had to add the Rejected Url “/?replytocom=” to avoid this cache behaviour.
