As I've read, the UE Law allows cookies to be exempted from the requirement of informed consent, if they satisfy one of the following criteria:
CRITERION A: the cookie is used “for the sole purpose of carrying out the transmission of a communication over an electronic communications network”.
CRITERION B: the cookie is “strictly necessary in order for the provider of an information society service explicitly requested by the subscriber or user to provide the service”.
Do you think that "wire" cookie satisfy this?
