Abstract: A method is disclosed for determining whether access to a host requested by a client session connection is permitted. After determining attributes of the client session connection, a list of hosts is selected based on the determined attributes of the client session connection. The list of hosts is then used to determine whether access to the requested host is permitted. The disclosed method can be used to allow for location-specific white lists of free URLs for a user at a wireless network hotspot that the user can access before being authenticated.

Abstract: A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.

Abstract: A method is disclosed for determining a whether access to host requested by a user is permitted. User identifying information is obtained using any of a variety of techniques. The method includes determining a user domain, which indicates an identity of the user's home service provider. A list of hosts is determined based on the home provider. If the requested host is in the list of hosts, then the user is allowed access to the requested host though the user is not authorized. The list of hosts may be determined by one or more attributes from an actual or implied user profile, such as a domain name.

Abstract: A fuel reservoir having a reticulated material, generally a felt or a foam, disposed therein is provided. The addition of this reticulated material, either alone or in combination with a viscous fuel, assists the prevention of undesired flow of the fuel, the minimization of undesired leakages, and assists in orientation independence and uniform distribution of the fuel in the reservoir. The reticulated material enables the use of a viscous liquid fuel that has fuel diffusion rates and fuel utilization characteristics that approach those of neat liquid methanol. The material also helps create a greater surface area for evaporation, thus allowing a highly concentrated, vaporous fuel substance to be delivered to an associated fuel cell.

Abstract: Systems and methods of processing incoming data provide for receiving incoming data and determining whether to employ stateless routing of the incoming data based on one or more destination hosts associated with the incoming data. In one approach, stateless routing involves storing the incoming data only in volatile memory and withholding confirmation of receipt of the incoming data until confirmation of delivery is received from either the destination host or a downstream router. The determination as to whether stateless routing should be employed can take into consideration historical data for the destination host as well as control data. The determination can also be based on the number of destination hosts.

Abstract: Indexed registers in controller chips are read in a two-step process. First, an 8-bit write instruction writes an index into an index register in the controller chip. Secondly, a 16-bit read instruction reads both the index register and a data register selected by the index from the index register. When index registers are read in a multi-threaded system, programs in two different threads could access the same index register, each writing a different index into the index register. When another thread over-writes an index written by a current thread, the wrong index and the wrong data are read by the current thread. The current thread detects that the index was overwritten by another thread by extracting the index from the 16-bit read and comparing it to the desired index. When the extracted index mis-matches, the current thread retries, again writing the index and reading back both the index and data.
