  2. Contents • Course Outline • Architectures • HTTP

  3. Course definition[1] • This course would deal with the advanced techniques for constructing better, efficient and robust web apps. It would briefly touch upon the major concepts ranging from simple HTTP to advanced semantic web.

  4. Stage 1 • Introduction to Web applications and review of basic concepts: client-server architecture, three- and n-tier models, static versus dynamic pages, server-database connectivity • Client-side technologies: HTTP protocol, HTML and related (CSS, JavaScript, etc.) • Using formal methods in the development of Web applications • The Model-View-Controller (MVC) paradigm • Web Services using RESTful

  5. Stage 2 • Introduction: Semi-structured data. • XML: core concepts • DTDs, a simple schema language for XML documents • XPath, a navigation language for XML documents • XSLT, a transformation language for XML documents

  6. Stage 3 • Introduction to the Semantic Web • RDF and RDF-Schema • Basics of knowledge representation and informal introduction to OWL • Protégé

  7. Client Server Architecture[2]

  8. 3-Tier Architecture[2]

  9. Multi-tiered Architecture[2]

  10. HTTP Application level protocol for distributed, collaborative, hypermediainformation systems.

  11. HTTP • Abbreviation for ? • A web crawler –user agent • Stateless protocol

  12. Maintaining State • Sessions • Cookies • Passing data at each request-response cycle

  13. Caching • What is caching? • What are the benefits?

  14. Caching (cont.) • Preventing Cache • Cache-control to no-cache • Allowing Cache • No cache-control header • Private: only the client can cache it. • Public: every intermediate node or the client can cache it.
