Not to use ignore-must-revalidate refresh_pattern for content.

So far, my approach has not caused a single problem with customers. And,
in my opinion, you're too insure fearing cache more aggressively. If I
complain about problems with the site - I'll write an exception. Do not
broke - do not fix it. But lowering cache hit by my own hands to
ridiculous values I will not ever. For whatever reason. Otherwise, it
makes no sense to put a caching proxy.
