DNS and cache-expiration modification

[Alberto ----]

never heared was possible even becouse is a populating on the fly from forwarders and TLD


cache is populated from answers and is not a physical zone


expiration is regulated from TTL ever send on answer and admin can change and specify different TTL per each record and different from SOA


for cache as is a dynamic populated area , I don't think is possibe to change what domain admin put as TTL and you receive as answer and put in cache

Subject: DNS and cache-expiration modification

Hello,

for heavy-use cache improvements, i was thinking to "alter" the expire time of cache records.
I would like to try to "alter" the expiration of records present in cache.

Do you know if with Bind is possible?

Thank you,
/F
