A computing environment that offers a level of decentralization wherein application server code resident on a remote application server can be distributed to a local server. The local server becomes a local application server for a client. A request for information by a client is serviced by the local application server. If the information is available on the local application server, the local application server satisfies the request using this information. If the information is not available locally, the local application server can access the remote application server to obtain the requested information. When the information is copied to the local application server, the local application server retains a copy of the information and forwards a copy to the client. Thus, subsequent requests can be satisfied without accessing the remote application server. Where the information cannot be transferred to the local application server, the local application server can establish a proxy to the remote application server that forwards a client request to the remote application server and a response from the remote application server to the client.

Disclosed are novel methods and apparatus for efficiently providing critical path analysis of a design. In an embodiment, an apparatus disclosed can assist in creating a single critical path schematic which can be used to simulate both rising and falling edge delays. This saves time as only one schematic and one simulation is required instead of the two generally required.

A method of demand based retrieval of a data file including pages of data, in a network system having a remote host system interconnected to at least one local host system via a first communication link, and one or more end-user systems interconnected to the local host system via a second communication link. A cache buffer is maintained in the local host system for storing a plurality of data pages. Upon receiving a request from an end-user system for the data file, the cache buffer is checked to determine if one or more data pages currently referenced by the request are available therein. If so, one or more of the available data pages are transmitted from the cache buffer to the end user system. Otherwise, the referenced pages are retrieved from the remote host system to the local host system via the first communication link, stored in the cache buffer in the local host system, and transmitted to the end-user system via the second communication link.

A method and apparatus for authenticating users. Prior art mechanisms require each individual application (running on an âapplication serverâ) that the user is accessing to provide for the ability to use the various authentication mechanisms. One or more embodiments of the invention externalize the authentication mechanism from the application in the form of a login server. Only the login server needs to be configured to handle authentication mechanisms. The application server checks if a request has an active and valid session (e. g. , a valid session may exist when there is active communication between a client and server that has not expired). If there is not a valid session, the application server redirects the user to the login server. The login server attempts to authenticate the user using any desired authentication mechanism. Once authenticated, the login server redirects the user back to the application server.

A method and apparatus for sharing resources in a network environment. An application running on a client can access a resource on a remote computer by submitting a request via an Internet browser. The request is analyzed, converted to proper format and is transferred over the network lines to a server that can satisfy the request. For security reasons, an application may not be authorized to submit a request directly to a server on the Internet. If a requesting application has a trusted status, then its request for connecting to the server is granted. If a request submitted by an application to a server is denied, then a server that entrusts the application is identified, and the request is submitted to that server. A program code called a âservletâ is implemented on that server to accept the requests submitted by a trusted application. The submitted requests are analyzed by the servlet and are forwarded to a resource server that can satisfy the requests.

A computing environment includes an application server code resident on a remote application server that can be distributed by a local server. A request for information by a client is serviced by a request handler on the local application server. If the information is available on the local application server, the request handler satisfies the request. If the information is not available locally, the request handler can access the remote application server. When the information is copied to the local application server, the request handler retains a copy of the information and forwards a copy to the client. Where the information cannot be transferred to the local application server, the request handler can establish a proxy to the remote server and a response from the remote application server to the client. The client communicates with the remote application server via the proxy on the local application server and is unaware of the remote application server.

A method for distributing code resident on a remote application server to a local server. When a client requests information, a request handler on the local server handles the request. If the information is available on the local server, the request handler satisfies the request using this information. If the information is not available locally, the request handler accesses the remote application server to obtain the requested information. The request handler forwards the information to the client and caches it on the local server. Where the information cannot be transferred to the local application server, the request handler establishes a proxy to the remote application server that forwards a client request to the remote application server and a response from the remote application server to the client. The client communicates transparently with the remote application server via the proxy on the local application server.
