Gaah. That's just stupid. This is such a _basic_ issue for caching ("if 
concurrent requests come in, only handle _one_ and give everybody the same 
result") that I claim that any cache that doesn't handle it isn't a cache 
at all, but a total disaster written by incompetent people.

Sure, you may want to disable it for certain kinds of truly dynamic 
content, but that doesn't mean you shouldn't be able to do it at all.

Does anybody who is web-server clueful know if there is some simple 
front-end (squid?) that is easy to set up and can just act as a caching 
proxy in front of such an incompetent server?

Or maybe there is some competent Apache module, not just the default 
mod_cache (which is what I assume kernel.org uses now)?
