摘要:
A method of managing connection requests from an application supported on a client. The client has a modem connectable to at least one server via a dialup computer network. According to the method, a list is maintained of the local Internet Protocol (IP) addresses assigned as modem connections are established to the dialup computer network during a session. The list is preferably in Last In, First Out (LIFO) order and includes a latest IP address as the last entry and one or more stale IP addresses. In response to a connection request associated with a stale IP address, the stale IP address is mapped to the latest IP address. The connection request is then redirected using the latest IP address. Preferably, client supports a proxy server which services the connection request locally if possible to avoid network traffic.

An Internet client is provided with a SOCKS server. The client comprises a processor having an operating system, and a suite of one or more Internet tools. The SOCKS proxy server includes means for intercepting and servicing connection requests from the Internet tools. Preferably, the proxy server has a predetermined Internet Protocol address, preferably the loopback address. If the loopback address is not available on the protocol stack, a redirecting mechanism is used to redirect connection requests associated with stale IP addresses to a current IP address. The SOCKS server includes a filtering mechanism for filtering connection requests to particular servers, and a monitoring mechanism for monitoring network IP activity.

A method for preventing time of check to time of use exploits includes receiving a system call from a user space at a system call intercept and copying user space parameters from the user space to a kernel space responsive to the system call. The method also includes copying the user space parameters from the kernel space to a secure location in the user space, receiving the user space parameters from the secure location at the system call intercept, and executing the system call based on the received user space parameters. A computer readable medium including computer readable code and a system for executing the method steps are also disclosed.

A computer implemented method, apparatus, and computer usable program code for creating normalized data from markup language data. User defined parameters are received for retrieving event data, wherein the parameters define a type of event and a subset of attributes for the type of event. In response to receiving the parameters, a process is configured using the type of event and the subset of attributes for the type of event to form a configured process. A set of records is processed using the configured process, wherein the configured process places data corresponding to each attribute in the subset of attributes for the type of event from the set of records into a table to form the normalized data.

A computer implemented method, apparatus, and computer usable program code for processing event data. In response to receiving an event, a size of the event data for the event is compared to a threshold size to form a comparison. The information about an event and event data is stored in a first entry in a main table in a database if the comparison indicates that the size of the event data is one that can be stored in the main table. The information about the event is placed in the first entry in the main table if the size is greater than the threshold size. The event data is stored in a second entry in an overflow table if the size is greater than the threshold size, wherein the entry includes a pointer to the first entry. The main table and overflow table form a live set and hold the current live data.

A method for transcoding an input stream to a desired output format using a transcoder framework. In response to a given transcoder of the framework recognizing an external reference that it cannot transcode, the method calls a subseries of specialized transcoders to transcode the external reference. After the subseries of specialized transcoders generates a transcoded external reference, that reference is returned back to the given transcoder, where it is incorporated into the transcoder's output. Transcoder sub-chains are used in this manner as modular, building blocks in the transcoder framework.
摘要:
A set of program elements (e.g., transcoders) are grouped together as an administrative unit. Instead of caching the individual outputs of each program element, preferably only the aggregate output of the set of program elements, taken as a whole, is cached. The inventive technique enables the effective re-use of intermediate content. In an illustrative client-server based implementation involving a transcoding service located at a server, the cached information may be shared across multiple server instances to obviate redundant processing. With the present invention, a caching mechanism in a complex software system may be extended in a user-configurable manner by setting up optimal intermediate caching points that are defined by groups of programs used in long computations.
摘要:
A method of managing events in a pervasive computing client device having a browser. Upon loading of a page in a browser window, the browser issues an outstanding HTTP request to a specified port. Thereafter, upon generation of an asynchronous event on another port, the routine identifies an appropriate message and builds a response to the outstanding HTTP request. The response, which includes the message, is then delivered to the specified port, whereupon the browser renders the message to the user. Thereafter, the browser automatically re-issues the outstanding HTTP request and waits for another asynchronous event.
摘要:
A method, computer program product and server for use managing connection requests to a pool of servers identified by a given URL. The method begins in response to a connection request from a given client machine that initiates a user session for associating a session identifier with a given server in the pool. The session identifier is then used to generate a “virtual” URL that redirects the connection request to the given server. Thereafter, any additional connection requests issued from the given client machine during the user session are redirected to the given server so that all content is served to the client from the same location. When the user session terminates, the virtual URL is inactivated and the given server is returned to the pool so that it can then be assigned a new user session to manage.
