    • A system and method for managing multiple proxy servers by a client computer. In one embodiment, the client computer's configuration is set to the fastest proxy server available. In another embodiment, a proxy table is accessed by the client computer to determine which proxy to use for a given web address. When a web address is included in the table, the corresponding proxy server is used to request the contents of the web address. If the web address is not included in the table, a default proxy server is used to request the information. In another embodiment, a periodic test is made to determine the speed of the current proxy server. If the speed is less than a predetermined threshold, the available proxy servers are all tested and the best-performing proxy server is selected. In another embodiment, aspects of each of the above-described embodiments are combined to provide a proxy server to a client computer based upon either a given web address (URL) or the fastest current proxy server.
    • 一种用于由客户端计算机管理多个代理服务器的系统和方法。 在一个实施例中,将客户端计算机的配置设置为可用的最快的代理服务器。 在另一个实施例中,客户端计算机访问代理表以确定用于给定网址的哪个代理。 当网址包含在表中时,相应的代理服务器用于请求网址的内容。 如果表中未包含网址,则使用默认代理服务器来请求该信息。 在另一个实施例中,进行周期性测试以确定当前代理服务器的速度。 如果速度小于预定阈值,则可以使用可用的代理服务器进行测试,并选择性能最好的代理服务器。 在另一个实施例中,组合每个上述实施例的方面,以基于给定的网址(URL)或最快的当前代理服务器向客户端计算机提供代理服务器。

    • A system and method for dynamically searching an identified web site. In one embodiment, a generic site search engine is invoked from any web page within the web site. Invoking the generic site search engine provides the user with an input display and displays resulting matches after searching pages from the web site. In another embodiment, a hidden HTML tag is used on web pages to identify the site specific search engine for the web site. When a user requests a site specific search engine from the user's web browser, the HTML tag is located and the corresponding web page containing the site specific search engine is opened. In another embodiment, if the HTML tag identifying the site specific search engine is not found, an analysis of the web site's root node is made to identify a site specific search engine. If a site specific search engine is identified through the analysis, the search engine web page is opened. In yet another embodiment, if the site specific search engine is not found through either a hidden HTML tag or by analyzing the web site's root node, a generic site specific search routine is invoked. The generic site specific search receives search parameters from the user and searches web pages from the web site to compile a list of matching web pages. The list of matching web pages is then displayed to the user for further selection.
    • 一种用于动态搜索所识别的网站的系统和方法。 在一个实施例中,通用站点搜索引擎从网站内的任何网页被调用。 调用通用站点搜索引擎为用户提供输入显示,并在从网站搜索页面之后显示结果匹配。 在另一个实施例中,在网页上使用隐藏的HTML标签来识别网站的特定于站点的搜索引擎。 当用户从用户的Web浏览器请求特定于站点的搜索引擎时,HTML标签被定位,并且打开包含站点特定搜索引擎的相应网页。 在另一个实施例中,如果没有找到标识站点特定搜索引擎的HTML标签,则对网站的根节点进行分析以识别站点特定的搜索引擎。 如果通过分析识别了特定于站点的搜索引擎,则打开搜索引擎网页。 在另一个实施例中,如果通过隐藏的HTML标签或通过分析网站的根节点找不到站点特定搜索引擎,则调用通用站点特定搜索例程。 通用站点特定搜索从用户接收搜索参数并从网站搜索网页以编译匹配网页的列表。 然后将匹配的网页列表显示给用户进一步选择。

    • A method and system for dual channel network connections where one channel can be used for normal data transmission and the second channel can be used for administration tasks such as correcting error on the data channel or running diagnostics. A first data processing system and a second data processing system communicate on a physical network by transmitting data packets on the network using a virtual private network (VPN). Data packets are transmitted through a first VPN channel. Administrative packets are transmitted through a second VPN channel independently of the first VPN channel. The data packets may be transmitted using Internet Protocol (IP), and a portion of the network may include the Internet. The data VPN channel and the administrative VPN channel share a single network interface card, hence only a single network interface card (NIC) is required for each data processing system.
    • 一种用于双通道网络连接的方法和系统,其中一个通道可用于正常数据传输,第二通道可用于管理任务,例如纠正数据通道上的错误或运行诊断。 第一数据处理系统和第二数据处理系统在物理网络上通过使用虚拟专用网(VPN)在网络上发送数据分组进行通信。 数据包通过第一个VPN信道传输。 管理分组通过独立于第一VPN信道的第二VPN信道发送。 可以使用因特网协议(IP)来发送数据分组,并且网络的一部分可以包括因特网。 数据VPN通道和管理VPN通道共享单个网络接口卡,因此每个数据处理系统只需要单个网络接口卡(NIC)。
