Subject: SharedCache (and probably other caches are incorrectly caching OPT records
Download (untitled) / with headers
text/plain 531b is incorrectly storing ephemeral pseudo OPT records; these are required for EDNS and are different from request to request and shouldn't be cached. The patch I have attached fixes SharedCache; a similar patch should probably be applied to N::D::Cache as well. You'll know you have this problem if you see the following error when using SharedCache and EDNS: You should not try to create a OPT RR from a string Not implemented at /usr/local/share/perl/5.18.2/Net/DNSServer/ line 136.
