weijin commented on TS-621:
---------------------------
Base on John`s solution, I also write a patch to cache empty documents. It`s
simple and have no need to modify the tunnel(http_sm). The patch have side
effects in cluster mode (3), if set force_cache_emtpy_doc, It can write empty
doc into another machine, but can not read it from that machine.
> writing 0 bytes to the HTTP cache means only update the header... need a new
> API: update_header_only() to allow 0 byte files to be cached
