Methods and media for exchanging data between nodes of disconnected networks are provided, including: determining a query type based on whether a query received at a first node includes at least one keyword or at least a portion of a uniform resource identifier; performing a search of a cache based on the query and the query type; converting the query into a formatted query document; storing the formatted query document in a database, if the search of the cache does not yield at least a predetermined number of data items; retrieving the formatted query document from the database at a predetermined interval; multicasting the retrieved formatted query document from the first node to at least a second node; and receiving, at the first node, a formatted response document from the second node, the formatted response document resulting from a search of a cache of the second node.

Methods and media for exchanging data between nodes of disconnected networks

In one embodiment, the method includes receiving a content request from the end user at a proxy. A modified TCP connection request message is generated such that the modified TCP connection request message includes a content identifier. The content identifier identifies the requested content. The modified TCP connection request message is sent from the proxy towards an origin server associated with the requested content, and a response to the TCP connection request message is received from a network element. A TCP connection is established with the network element.
