1) This will work only if you'll switch off ETag's as well.

2) This isn't a solution, but a bandaid.  It won't fix the real 
problem (mtimes mismatch), but will make response with greatest 
mtime eventually win.  Even with only 2 servers used this 
will still result in about 1.5x more 200 responses than needed.
