Well that makes sense now. I see that other headers are corrupted.

Which brings us back to my question - what is the best way to
force-refresh a page in cache? I want my backend to invalidate some
pages as they change. And those pages could have SSI inside. I know that
deleting a file from hdd works, but my invalidation requests will happen
many times, removing and recreating files again and again could have
performance impact. And it seems just wrong. Any help here?
