Abstract

A method and system for serving content from a peer server in a photosharing peer-to-peer network is disclosed, wherein the peer server stores a web album and at least one associated digital image. Aspects of the invention include prior to the peer server going off-line, the peer server initiates a synchronization with a proxy server and a guest content server in which the web page a web page descriptor defining the web album is copied from the peer server to the guest content server, and the image associated with the web album is copied from the peer server to the proxy server. In response to a request from a requesting computer to view content stored in the peer computer when the peer server is off-line, the request is fulfilled by forwarding the web page from the guest content server to the requesting computer, and forwarding the image associated with a web page from the proxy server to the requesting computer, thereby successfully serving content from the peer server even when the peer server is off-line.

Claims

1. A method of providing access to a peer server protected by a firewall, the method comprising:

receiving from a requestor, at a proxy server, a URL request that identifies the peer server;

accessing a server table having a plurality of peer names and socket information associated with each peer name of the plurality of peer names to determine if the peer server is registered with the proxy server;

creating a peer request packet based on the URL request;

passing the peer request packet to a peer manager associated with the proxy server where the peer manager finds a socket connection to the peer server;

passing the peer request packet to the peer server;

receiving a response including a peer response packet from the peer server;

converting the response into a URL request response; and

sending the URL request response to the requestor.

2. The method of claim 1, wherein a servlet thread associated with the proxy server receives the URL request.

3. The method of claim 2, wherein the servlet thread creates the peer request packet and passes the peer request packet to the peer manager.

4. The method of claim 1, wherein the peer response packet received from the peer server is a chunk of a response such that the response includes a plurality of chunks represented by a plurality of peer response packets where the proxy server reassembles the plurality of chunks from the plurality of peer response packets during the conversion of the response to the URL request response.
