[dnsdist] How to list all entries in cache?

[jiang-wd at 139.com]

Hi,

I've tested PacketCache:dump, but can not find response infomation.
Can you give me any advice? Thanks.

# dnsdist -c
> getPool(""):getCache():dump("/tmp/cache.txt")
Dumped 15 records

# find /tmp -name cache.txt | xargs -i cat {}
; dnsdist's packet cache dump follows

You can use the dump() [1] method on a PacketCache object to dump a 
summary of the cache content to a file.
