A system and method for automatically mapping of hypertext input fields to software components. The system includes a hypertext preprocessor, a name-space manager, a data handler, and a component manager. The hypertext preprocessor examines the hypertext input field names and uses the name-space manager and component manager to determine the mapping between input field names and software component properties. When the hypertext page is rendered, the name-space manager registers the mapping between each submitted input field and the corresponding component property. When the input data is submitted, the data handler uses the name-space manager to find the component property for each submitted input field and uses the component manager to convert the data to the correct type before calling the appropriate component method to set the property value.

The system and method interface and separate formatted content and program code in connection with a content server system. The system includes a document preprocessor, a compiler, and an execution context manager. The document preprocessor parses and analyzes a formatted content document that contains program invocations and translates the program invocations into a procedure having program code suitable for compilation or intepretation. The preprocessor also encodes designated segments of the content document as subprocedures which are invoked within a context managed by the execution context manager. The execution context manager allows values to be mapped to named parameters so that the values are available to the invoked procedures and programs. As a result, the content server system provides separation between the formatted content and program code.

A computer system for a web site uses three tiers of servers, web (or HTTP) servers, application servers, and backup servers. The backup servers are responsible for backing up the session data for particular application servers. The system assigns to each web session a session ID, which encodes the IP addresses of the application server and its backup server, and provides an identifier that uniquely identifies the session within that application server. A session is automatically routed to a second application server to process a request if the application server handling the session should fail or not have the requested application. However, the request uses the original session ID. The second application server detects from the session ID that the session may have been handled by the first application server. The second application server decodes the IP address for the backup server for the first application server, and connects to that backup server. The user's session data is recovered from that backup server and reconstituted into a new session, with a new session ID. If the session had previously existed on the second application server, the session ID used by the second application server and the session data for that session are used, updated with the session data from the first backup server.
