There is a blog that I would care never to read again, even in moderation. I added the blog to my localhost list so now I can't visit the blog anymore. But my lizard-brain has found a workaround: if I google the blog I can read Google's cache. Is there a way to block Google's cache of the blog without blocking the rest of Google's functions?
Depends on the amount of effort you are willing to spend. I have a local Squid caching proxy (maybe privoxy or 3proxy or something else is better for you), I have set up URL rewriting and among other things I block some URL patterns for various reasons. It is not too hard to set up and there are various ways to do this with various proxies.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
