....for future mobile workstations. The World Wide Web (WWW) 4] is a globally used distributed collaborative information system that has a rapidly increasing user community. Hence, there is real interest for bringing WWW to the mobile workstation. However, the HyperText Transfer Protocol (HTTP) [5] used by the World Wide Web exhibits a number of performance problems which need to be solved to make HTTP a practical tool on a weakly connected mobile workstation. In this paper we examine these problems in detail. We show how to address these problems within our architecture. Our goals are: 1) ....

....plain text or postscript) are treated depends entirely on the WWW client software. 2.2 HyperText Transfer Protocol The HTTP protocol is a stateless protocol designed to transfer data objects between a WWW client and a WWW server. It is currently being standardized within the Internet community [5]. Each HTTP transaction consists of a single HTTP request and of the associated response. The request begins with a request line specifying a document object and an operation. 1 The response starts with a status line announcing the success or failure of the request. These are followed, ....

....Science Foundation Presidential Faculty Fellowship. Dahlin was also supported by an NSF CAREER grant (CCR 9733742) and end to end semantics could be provided by taking into account a myriad of more dynamic factors, such as server CPU loads, network congestion, and client reference patterns [10, 74, 11], suggesting the need for a more general architecture for mapping names to services. More broadly, academic and industrial researchers have proposed a bewildering array of new services for mediating between clients and servers; again, we believe this argues for rethinking the architecture for ....

....the subscription to stream events, the finish method the unsubscription, and the event method the reception of stream events. The HTTP handler handles World Wide Web communication and forwards parsed HTTP messages to other objects. A DCG parser could easily be derived from the HTTP specification [6]. Objects can subscribe to a specific path whereby web accesses matching that path will be forwarded to the subscriber. The following system objects subscribe to HTTP events: ffl htmlserver Subscribes to the empty path and receives all web requests not catched by other subscribers. Replies ....

There are also a number of Tcl commands to access services provided by other Internet protocols like ICMP, NTP, DNS as well as some well known SUN RPC services [11] The delegation server interacts with the delegation client using the HTTP protocol [2] which makes transfers of large management procedures efficient. 2 The implementation of a software environment which allows to experiment with different organizational models requires to solve a number of problems (e.g. access control, authentication, resource control, naming, group management, ....

....gives us two types of hooks that can be useful. 1. Time To Live (TTL) values, attached to cached objects (HTML pages) Upon its expiration, the source of the object can be contacted to update the page. 2. A source can be contacted with an if modified since (a header field in a http) request [BLET95]. This requests the server to respond to the request only if the requested object has been modified since the specified time. If it has not been modified, the client continues to use the cached object, else it caches the new object. Given this, the crucial issue is the setting of the TTL values ....
