I'm not sure I understand. I have control over the back end, the front end, the middle end, all the ends. However, I thought the problem was there was no way to get varnish to read the header without loading the file into the cache? If that's not true, then shouldn't Content-Length be enough?

I'm assuming that in this case it's not possible for you to have the backend server emit an appropriate Cache-Control or Expires header based on the size of the file? The server itself will know the file size before transmission, and the reindeer caching games would not be necessary. ;-) That's definitely the Right Way, but it would require control over the backend, which is often not possible. Apache unfortunately doesn't have a built-in mechanism/module to emit a header based on file size, at least that I can find. :-( -- kb On Tue, Mar 15, 2011 at 00:42, Chris Hecker <[email protected] <mailto:[email protected]>> wrote: Yeah, I think if I can't do it Right (which I define as checking the file size in the vcl), then I'm just going to make blah.com/uncached/* <http://blah.com/uncached/*> be uncached. I don't want to transfer it once just to throw it away.

All the other solutions mentioned in between are far more intelligent and much more likely to backfire in some way or another. Just my 2 cents.

I can put it in a directory and tell varnish not to cache stuff that matches that dir, but I'd rather just make a general rule that varnish should ignore >=20mb files or whatever.
