<div>Say a site like tumblr is using varnish, which has thousands and thousands of blogs, and so many blog entries are being updated via comments etc. How realistic would sending 1K ban's be to varnish?</div></blockquote>

<div>Maybe I have misunderstood this, but I'm guessing their are ruby/java client libraries that when content gets updated in a web application, I could then send a request using the ruby/java client library to ban a specific item from cache right?</div>
