摘要： A process for opening and reading a file over a network, including a WAN. An edge file gateway receives a request from an application to open a file cached with the edge file gateway at one point on a network and stored on a file server connected to a central server at another point on the network. The edge file gateway forwards the request to open the file to the central server, along with any offsets and lengths stored from any previous requests to read the file. The central server responds by sending any file data described in the offsets and lengths to the edge file gateway. When the edge file gateway receives a read request, the edge file gateway stores the offset and length for the request, if a predefined storage limit is not exceeded, and attempts to satisfy the request from cached file data.

摘要： HTTP layered reconstruction is disclosed. A database is queried to identify a location of a previously reconstructed HTML artifact file or packet data of a HTML file in a repository that stores packet data captured from a network. The reconstructed HTML file is analyzed. Links to external files are identified and the database is queried to identify a location of previously reconstructed artifact files or packet data of associated external files. The external files are reconstructed, as needed. A web page is then reconstructed based on the reconstructed HTML file and reconstructed external files, presenting a view of the web page as it originally appeared to a user. A user may specify which external file types to include and/or not include. New versions of external files may be obtained and indicated in the reconstructed web page when associated artifact files or packet data are not stored within the repository.

摘要： An exemplary embodiment provides for methods, apparatuses and systems to facilitate the detection of network device failures in a variety of network topologies. This is accomplished by equipping a network device, or other devices used in conjunction with network devices, with a bypass port or network interface, such as a secondary outgoing network traffic communication port. In a normal operating mode, network traffic received at a first network interface or port is forwarded, after processing on the packet processing path of the network device, from a second network interface or port. In one implementation, the second network interface or port and the bypass port or network interface are connected to corresponding interfaces of a router or two routers. When a network device failure occurs network traffic bypasses the packet processing path of the network device and is forwarded from the bypass port or interface.

摘要： A cache logically disposed in a communication path between a client and a server receives a request for a content item and, in response thereto, requests from the server header information concerning the content item and an initial portion of data that makes up the content item. The cache then computes a first hashing value from the header information and a second hashing value from the initial portion of data. A content identifier is created by combining the first hashing value and the second hashing value. Using the content identifier, the cache determines whether a copy of the content item is stored by the cache; and, if so provides same to the client. Otherwise, the cache requests the content item from the server and, upon receipt thereof, provides it to the client.

摘要： In one embodiment, a method includes receiving an address of a DNS server of a network. A secure communication tunnel is established with a client of the network. The client is notified that requests to the address of the DNS server of the network should not pass through the secure communication tunnel. A request for a DNS lookup of a name of a host of the network is received through the secure communication tunnel. A DNS referral that includes the address of the DNS server of the network is sent to the client.

摘要： Various techniques are described to authenticate the identity of a proxy in a client-proxy-server configuration. The configuration may have a client-side and a server-side SSL session. In the server-side session, if the proxy has access to the private keys of the client, the proxy may select a client certificate from a collection of client certificates and send the selected certificate to the server to satisfy a client authentication request of the server. If the proxy does not have access to the private keys, the proxy may instead send an emulated client certificate to the server. Further, the client certificate received from the client may be embedded within the emulated client certificate so as to allow the server to directly authenticate the client, in addition to the proxy. An emulated client certificate chain may be formed instead of an emulated client certificate. Similar techniques may be applied to the client-side session.
摘要翻译：描述了各种技术来验证客户端 - 代理服务器配置中代理的身份。该配置可能具有客户端和服务器端SSL会话。在服务器端会话中，如果代理可以访问客户端的私钥，则代理可以从客户端证书的集合中选择客户端证书，并将所选择的证书发送到服务器以满足服务器的客户端认证请求。如果代理无权访问私钥，代理可能会将仿真的客户端证书发送到服务器。此外，从客户端接收的客户端证书可以嵌入在仿真的客户端证书中，以便除了代理之外，允许服务器直接认证客户端。可以形成模拟的客户端证书链，而不是模拟的客户端证书。类似的技术可以应用于客户端会话。

摘要： The present invention describes a system, method, and article of manufacture for resolving names received in network protocol requests by a network intermediary device coupled between a client network and a server network. A deferred trust model caching engine in the network intermediary device includes a transactor module configured to efficiently process a protocol request with a sequence of determinant criteria, although the sequence can occur in different orders. The deferred trust model caching engine includes a cacheability evaluator component configured to determine whether the protocol request is for a resource that the protocol permits to be cached by the network intermediate device, and a supplier trust evaluator component configured to compare information about the client's network protocol request and a cached object representation to determine if the object is trustworthy or not. The cached object representation associates an object with a supplier identity and a supplier trust property.

摘要： A host computer system is categorized according to uniform resource locator (URL) information extracted from a digital certificate purportedly associated with said host. Thereafter, a secure communication session (e.g., an SSL session) with said host may be granted or denied according to results of the categorizing. If granted, messages associated with the secure session may be tunneled through a proxy without decryption, or, in some cases, even though the secure communication session was authorized messages may be decrypted at the proxy.
摘要翻译：主计算机系统根据从与所述主机相关联的数字证书提取的统一资源定位符（URL）信息进行分类。此后，可以根据分类的结果来授予或拒绝与所述主机的安全通信会话（例如，SSL会话）。如果被许可，则与安全会话关联的消息可以通过代理进行隧道传送而不进行解密，或者在某些情况下，即使安全通信会话被授权，消息也可以在代理处被解密。
