Systems and methods for recording and replaying client-server transactions on selected clients in order to gauge the performance of the client-server system from the perspective of the client. In one embodiment, a method comprises playing back a set of recorded transactions on a client, monitoring selected performance-related parameters at the client, and transmitting monitored data to the server for analysis or for viewing by a system administrator. The set of transactions is recorded on a first client by replacing a standard Internet transaction driver (e.g., WinInet.DLL) with a modified driver that is configured to intercept function calls. The function calls and corresponding parameters are recorded in a file which is later transmitted to a client, where the recorded transaction information is used to reproduce the transactions on the client. As the transactions are played back, performance data may be monitored and forwarded to a management server for analysis, display, etc.

An improved system and method for presenting computerized interactive forms (such as survey questionnaires, employment applications, etc.) via the Internet to human respondents making use of client computers. The invention is a cross-platform web application written in Java and JavaScript. The presented questions / items are selected dynamically as a respondent fills in the information for each question / item. A code-length-reducing software architecture—wherein all objects are widgets—along with a design choice of inheritance makes for maximum code clarity, impressive code compactness, and swift parsing. More information and a higher quality of information are collected from a respondent, because waiting time is reduced and only relevant questions are presented. Implementation of parent-child containment in the widget set, coupled with a JavaScript skeleton design system, facilitates respondent-friendly display design by interface designers, and a rapid design process.

In a client-server system, a server-node application runs a user session and a remote presentation protocol communicates between the client node and the server node. The server node stores a remote virtual desktop including remote windows of the user session. The client node displays multiple local windows of applications running locally on the client node and further displays one or more windows of the remote virtual desktop. The one or more windows are clipped to produce a clipped region so that the remote windows are displayed therein to appear as the local windows. The local windows are enumerated according to z-order from back to front and an area of each local window which overlaps the clipped region is subtracted from the clipped region so that the local windows show through the area.

The present invention relates to a client-server system having a security system for controlling access to application functions. The security system separated from the clients and the application functions routes all incoming requests created by various PVC-devices to a centralized security system providing an authentication component and a security component. The authentication component provides several authentication mechanisms which may be selected by information contained in the client's request. The authentication mechanism may be changed or extended without changing conditions on the client as well on the server or application side. The security component provides a security policy describing security requirements for accessing application functions which may be invoked by the security component. If the selected authentication mechanism succeeds and fulfills the security policy associated to that application function then the application function will be invoked by the security component.

A method for single sign-on in a client-server system including a server and a client and a remote presentation protocol based on ITU T.120, communicates between the client node and the server. The client obtains a ticket for a user operating the client. The ticket identifies the security context of the user on the client. Upon connecting the client to the server, the ticket is transferred from the client to the server. The server authenticates the ticket with a security authority and when authenticated the server receives from the security authority a security context for the ticket. When the client so requests, applications are launched using that security context. Preferably, the server is a Microsoft Terminal Server and the remote presentation protocol is Microsoft Remote Desktop Protocol (RDP). The ticket transfer preferably uses a channel within the remote presentation protocol, such as an RDP virtual channel.

Client-server system for providing web site preview information of web site content and features to users. The user enters a web site URL they want to preview into a client application, which generates preview information about the web site content and features. The client generates the web site preview information by building the preview information from preview information sources including the web site and / or requesting preview information from the server / back-end of the client-server system. Both the client and the server build preview information by accessing preview information sources such as web pages and web page information databases, extracting the requested preview information, formatting the preview information in a standard preview format, and returning the preview information to the user for display. While the client and server system build preview information from preview information sources in real-time, the server system also builds preview information in non-real-time by storing preview information in a preview information archive, and transmitting this pre-built preview information to clients in response to client preview information requests. In addition to providing web site preview information, the present invention may also be used to provide real-time or near real-time promotional information associated with a web site. The promotional information or announcement may be provided in conjunction with the preview information presented to the user. Specifically, when the user requests or is provided with preview information for a particular web site, the system “goes” to the web site and retrieves announcement information prepared by the web site sponsor. The announcement information may be in the form of an HTML file prepared by the web site's owner or marketing / promotional team. The HTML file is then presented to the user in conjunction with the presentation of the web site preview information.

A load distribution method is adopted by a client-server system comprising a plurality of clients 100 and a server cluster 1100, which includes a plurality of servers 800 each used for processing requests made by the clients 100 and allows the number of the servers 800 to be changed dynamically. Each of the clients 100 detects the number of servers 800 composing the server cluster 1100, sets an allocation of requests transmissible out to a newly added server 900 at a value small in comparison with that set for each of the other servers 800 right after detecting an increase in server count and then transmits out requests to the servers on the basis of the set allocation. It is thus possible to provide the clients 100 and the server-cluster system 1100 with the load distribution method suitable for a cluster reconfiguration technology for changing the number of servers composing the server-cluster system 1100 in accordance with an increase and a decrease in demand for a service.

A client-server system may include a primary state of session data. One or more application servers may include client states of the session data and may be configured to access the primary state. The session data may include one or more attributes. The distributed store may lock the primary state for access by a process executing on one of the application servers. Information may be maintained on which attributes are mutably accessed by the process. An object graph comparison of the mutably accessed attributes and a benchmark version of the attributes may be performed to determine which of the mutably accessed attributes were actually modified. The modified attributes may be used to synchronize the primary state with the client state.
