whether squid application of the machine and the client will get different Name Resolution ( A records)at cdn ( balance or random ) environment .

[johnzeng]

Hello Dear Sir :

i have a question , i have run squid ( tproxy mode ) and bind9 at a same
machine , and dns server ip of full client is the machine ip too

and when a client try to send dns request to the same machine and squid
application of the machine send same request to local machine ( same

machine ) , i hope A record will be same . but maybe squid application
of the machine and the client will get different Name Resolution ( A
records)

at cdn ( balance or random ) environment .


whether we can force BIND to realize same Name Resolution ( A records) ,
i search named.conf detail and *found the command ***rrset-order fixed )
*will be suitable *, but fixed will be support by BIND 8 ,

and i use BIND 9 now , if possible , please give me some advisement


Thanks

John
