the web server, the machine that the web server runs on, or by the network of servers and resources that the web server is connected to. For example, one of the most basic functions of a Web server is distributing HTML files. In this case, a web browser requests a given HTML file from the web server. In response, the web server will find the given file on the local (or networked) file system and send it back to the browser. The web server has at its disposals a whole world of resources beyond file systems. Web servers are in close contact with all sorts of resources including data stores, applications, business objects, operating system resources, authentication services (server-based or directory services like LDAP/ADSI) and more. Although Server Side Processing has many advantages, it also has some disadvantages. For example, the useful things done with SSP are static, and can be generated when a document is generated. Parsing a source document once to generate the documents actually served will use much less CPU than parsing the document every time it is served.To select between documents, having the server select between static documents takes much less CPU than parsing the HTML as it passes through the server. Furthermore, SSP doesn't work with caches. If a document is cached, users start seeing the wrong version of the document. For the cases where the document is not cached, it must be re-fetched - even if unchanged - for every load. This increases the network load across the entire network. And because the average end-user bandwidth goes down instead of up, this is quite a disadvantage. In conclusion, SSP appears to serve no useful purpose which pre-processing documents cannot provide. Further, it causes both extra CPU usage on the server and extra bandwidth usage on the entire network while doing so.A client is a computer used to access network resources and a server is the networked computer that responds to client request...
