Client software

The client software consists of an HTTP proxy and a set of publishing tools. An individual wishing only to retrieve Publius content just requires the proxy. The proxy transparently sends non Publius URLs to the appropriate servers and passes the returned content back to the browser. Upon receiving a request for a Publius URL the proxy first retrieves the encrypted document and shares as described in Section 3.3 and then takes one of three actions. If the decrypted document successfully verifies, it is sent back to the browser. If the proxy is unable to find a document that successfully verifies an HTML based error message is returned to the browser. If the requested document is found to have been updated then an HTTP redirect request is sent to the browser along with the update URL.
