Web technologies: a computer science perspective by Jeffrey C. Jackson

By Jeffrey C. Jackson

Net applied sciences: a working laptop or computer technology viewpoint is perfect for classes in Web-based platforms (aka Web/Internet Programming/Systems) in laptop technological know-how, MIS, and IT departments.  This textual content introduces the main applied sciences which were constructed as a part of the delivery and maturation of the realm vast net. It presents a constant, in-depth therapy of applied sciences which are not likely to obtain certain insurance in non-Web laptop technology classes. scholars will locate an ongoing case learn that integrates a large spectrum of net applied sciences, assistance on establishing their very own software program environments, and numerous workouts and venture assignments.

Example text

If the TCP connection is kept alive, the server subtask continues to monitor the connection until a certain length of time has elapsed, the client sends another request, or the client initiates a connection close. A few definitions will be helpful before proceeding to more detailed coverage of web server features. First, all modern servers can concurrently process multiple requests. It is as if multiple copies of the server were running simultaneously, each devoted to handling the requests received over a single TCP connection.

A user saves a document in Mozilla under the File|Save Page As menu. r Find in page: Standard documents (text and HTML) can be searched with a function that is similar to that provided by most word processors. In Mozilla, the find function is accessed under the Edit|Find in This Page menu. ) r Automatic form filling: The browser can “remember” information entered on certain forms, such as billing address, phone numbers, etc. When another form is visited at a later date, the browser can automatically fill in previously saved data.

User-Agent A string identifying the browser or other software that is sending the request. Accept MIME types of documents that are acceptable as the body of the response, possibly with indication of preference ranking. If the server can return a document according to one of several formats, it should use a format that has the highest possible preference rating in this header. Accept-Language Specifies preferred language(s) for the response body. A server may have several translations of a document, and among these should return the one that has the highest preference rating in this header field.
