Abstract
A method for requesting proof of delegation for delivery of content to a client terminal via an encrypted connection. The content is referenced on a content server, to which the client terminal emitted a request to obtain the content. The content server has delegated the delivery of the content to a primary delivery server. The method is implemented by a secondary delivery server, to which the primary delivery server has delegated the delivery of the content. The method includes: receiving a request to establish an encrypted connection, from the client terminal, including an identifier of the content server; emitting a request for proof of delegation of delivery, addressed to the content server; receiving of a message from the content server, including an encryption key; emitting a response for establishing an encrypted connection, addressed to the client terminal; and establishing the encrypted connection with the client terminal using the encryption key.
