there seems to be no-cache directives in both of them. if so shouldn't
TCP_MISS be TCP_CLIENT_REFRESH_MISS instead ? or is that because the file is
already released from the cache ? this is not that important.

but the file still gets released after the TCP_CLIENT_REFRESH_MISS on the
HEAD, i still feel that this is not 100% good. what do you think ?

thanks,

alex
