One of my clients runs a site that gets heavy numbers of comments on every post and a lot of activity by the authors of those comments. The result is that I see a lot of BYPASS in the access.log, and the server is having to render everything dynamically for those users constantly because they have the comment_author_ cookie.
Using nginx-helper, I have it set to purge a page when a comment is published for that post.
So my question is, do we really need to BYPASS the cache for comment authors? Given that nginx-helper is purging as soon as each comment is posted, won’t comment authors already get a freshly generated page?
Has anyone experimented with this?
