Fix handling of SSL/TLS exceptions allowing errors to be ignored for a session

Browse Source 
Not persistent  but I'm not  sure they need to  be as sites  we access
should have valid certificates and  chains of trust. This should allow
users  with  baulked SSL  installations  or  incomplete CA  stores  to
proceed with network accesses at their discretion.
