....compression is applied to the stream of data communicated across the client to base link, rather than to individual messages alone. 2 Basic Web Browsing The Hypertext Transfer Protocol (HTTP) defines the interface which enables web browsing. This study is based on version 1. 0 of this protocol [3]. The HTTP protocol allows for simple transactions between clients and servers using a request response message pair. HTTP transactions are conducted over Transmission Control Protocol (TCP) connections; a connection is established for each transaction, and closed once the transaction completes. ....

....The server acts like a HTTP server regarding its clients. Incoming client requests are parsed to extract the request parameters such as URL, WIDTH, HEIGHT, etc. of Web page thumbnails. The HTTP protocol allows users to request thumbnails directly from the Web browser according to RFC 1945 [4]. That offers the opportunity to simply integrate dynamically generated thumbnails into Web pages. Neither are specific client applications nor Web browser plug ins necessary merely a Web browser is required as a client. Alternatively, self implemented client programs such as Java programs, ....

Alternatively, self implemented client programs such as Java programs, browser plug ins, cgi scripts, servelets etc. can be used to access the server. The request format is designed to be HTTP compliant. Each request is encoded as an HTTPGET [4] request. The general request syntax (in EBNF notation) is as follows: request : http: server name [ port ] url= url f options g . 3.3 Web Page Rendering Our implementation uses the current Netscape version installed on the server host as rendering engine.

The Open DSS Protocol is a general protocol that provides facilitated access to DSS utilizing the existing Internet application layer protocols HTTP and HTML [3, 12], and consists of two layers. The first layer in the Open DSS protocol is the Metainformation Layer. It indicates the Web site contains a DSS and includes all of the information necessary to completely explain the DSS. The second layer is the Transaction Processing Layer. This layer is responsible ....

The hypertexts served by the WWW are not restricted to text. Other media such as images, graphics, sound, and movies can be referenced [BLFN94]. The documents are assembled to form the layout of WWW pages, containing noncontinuous media which are typically loaded first and presented afterwards. Even interactive elements, such as forms, use the same request response mechanisms as other protocols e.g. FTP, SMTP, GOPHER. The Web has ....

....The initial draft of the protocol was based on that used by the Digest Authentication Scheme [8] Digest uses structures within HTTP to transfer information between the client and the server. The structures used are the WWW Authenticate header and the Authorization Request header in HTTP 1. 1 [1]. Digest has its own specification for what goes in those headers and it was used as a model for the initial draft. However, the initial version of the protocol has been modified; Terrance wrote his thesis before much of the SPKI SDSI client and server were developed. 44 The original ....

....one needs to carefully consider what information needs to be present in the tag. The specified tag format needs to be such that will allow the server administrator flexibility in implementing their desired security policy. The main considerations are to have the tag specify either just the HTTP [1] method and location, or to include other state information such as allowed client IP Address and allowed time range for access. These options would allow the server administrator to specify a stricter security policy for their website. 5.3.11 User Certificate Management The user has both the ....

To coordinate these tasks, a process support system should provide for distributed process execution and integration with tools across networks. We describe the use of Hypertext Transfer Protocol (HTTP) [1], an increasingly ubiquitous technology, to provide a coordination mechanism for distributed execution of process and tool integration. Building on the Endeavors process support system[2] we can use extensions to an HTTP server to provide support for communication and coordination between system ....

There are many examples of applications such as TELNET and FTP running transparently over SSL. However, SSL is most widely used as the secure transport layer below HTTP [5]. A large number of e commerce sites dealing with private and sensitive information use SSL as the secure transport layer. This number is expected to grow as more and more businesses and users embrace electronic commerce. As security becomes an integral feature of Internet applications and the use ....

In the following Sections, we describe such related research. 5.9.1 Proxies Luotonen and Altis [78] introduced the WWW server proxy to help people behind a closed network access the Web. Conceptually, a proxy is a special HTTP [11] server capable of receiving requests from clients inside a closed network and retransmitting them to the actual server outside the closed network. Due to the aggregation level attained through proxy, caching becomes the natural solution and, in fact, many proxy servers with caching have been ....

This metric is required for modeling of realistic Web sites and workloads. For example, with the HTTP 1. 0 protocol [3], a separate TCP connection is required to retrieve the base HTML object and every object embedded in it. The default persistent connection behavior of the HTTP 1.1 [6] however, allows multiple HTTP request response pairs to be transmitted over a single TCP connection. Knowing a realistic ....
