Subject: Re: [wsrp-markup] Handling of attachments and/or large markup responses
Carsten, Interesting, now I have 2 questions. (1) I've just looked at the JAX-RPC spec and it requires SOAP- attachments for handling attachments. Would you give a pointer to the interoperability information you are mentioning? (2) Are you suggesting that a producer would bundle up all static resources with the getFragment response and the consumer would cache them so when the call of the client comes to the consumer -to the resource [proxy] URL- the consumer has already the resource and it does not need to make a call to the producer? Something like a pro-active cache?
