Session Ticket sizes
About Session Tickets
Session Tickets are an extension used in resuming previous TLS connections. Clients send an opaque session ticket (previously supplied by the server) in the Client Hello.
This table lists popular sizes of session tickets, useful for censorship circumvention tools that use this extension to covertly send tagging or other session information.
65.16% of Client Hello messages include a Session Ticket extension. Of those, these are their sizes:
