Does LTM cache DNS entries in ramcache if no web acceleration profile applied to the virtual server
Trying to understand how DNS caching works on the LTM. If I do not apply a web acceleration profile to that virtual server will it cache DNS entries in ramcache? My virtual server uses an irule RESOLV::lookup b/c the back end server ip may change. I need for it not to cache the dns entry. I see that I can configure a web acceleration profile and then exclude links but is that necessary if I don't apply any web acceleration profile? What gets written to ramcache? if I don't do anything and leave the system defaults will it save to ramcache? When I run show ltm profile ramcache all - it shows 0 records.
