objective c - How do I get CFNetwork operations to stop trusting a certificate -

i have set app allow switching ssl certificate validation on , off based on url using mechansim outlined here: objective-c/cocoa: how take bad server certificate?

this sets client take 'bad' certificate server. problem subsequent calls same server finish correctly, if set have strict certificate checking.

i assume underlying cfnetwork implementation caching certificate , 'trusted' status. don't want behaviour.

is there way either turn off certificate caching in general/for specific request, or @ to the lowest degree purge cache

try using os x keychain access utility examine login keychain. can delete or alter trust policy of cached certificates there. there command-line interface: /usr/bin/security.
