No special information from the client about the cache.

The client cannot use the cache, at this time we're not discriminating why but possible reasons include cannot establish TLS connections, routing failures, PMTUd black holes, or potentially some form of fraud detection (but thats hard!).

XXX: See similarities to ContentRequest.

Signed by escrow key; ensures that the key that produced the batch signature is authorized.

XXX: Remove me! This is not used over the wire; it's used only in the `cache` package.

Client-to-publisher.

Response to a ContentRequest.

XXX: return a response or error if we reject the escrow?.

GetBlocksRequest wraps up the requests for blocks.

XXX: Is this a good name if this message includes a port number?.

TODO: this struct is also used at the cache, but most of these fields are irrelevant for the cache and only relevant for the publisher.

XXX: This needs a better name.

Contains enough data to let a cache recompute/verify the ticket-bundle digest.

XXX: I suspect that the ticket number may be the only thing here's that's actually important, since it could be used in proofs of double-spending (on the CP's behalf).

By the time the L2 ticket is decrypted by the client, all of the caches must have provided data and outer encryption keys to the client; these are the inputs to the colocation puzzle, whose output is used to decrypt the L2 ticket.

This is what the client will present to the cache.
