The Complete Course of HTTP and Web Services

Define uri and url and explain their syntax and distinctions. Present http methods like get, post, put, delete, headers, status codes, caching, and api concepts in a stateless model.

Explore HTTP methods like get, post, put, and delete, their data handling, and when to read, submit, update, or remove resources.

Learn how http headers, including request and response headers, use content-type, accept, encoding, language, and cookies to enable client and server communication and status codes.

Examine http basics, including statelessness, http methods (get, post, put, delete), headers, and status codes. Focus on rest api, https security, and caching; gain hands-on testing with Postman.

Explore the anatomy of an http request, including the request line, headers, and body, and compare get, post, put, and delete methods with header usage.

Explain how http request headers convey metadata between client and server, including key-value header pairs like content-type and user-agent, and demonstrate get, post, put, and delete flows with real-world examples.

Analyze the anatomy of an http response, including status codes, headers, and body. Understand how headers like content type, encoding, cache control, and location guide clients.

Explore the five http status code ranges from 1xx informational to 5xx server errors, and learn codes like 200, 201, 301, 302, 303, 307, 400, 401, 403, 404, and 500.

Handle http status codes and errors within a web app by using try and except blocks, displaying user-friendly messages for client and server errors, and guiding redirects and logging.

Explore http cookies and sessions, including set-cookie headers, browser storage, and name-value data pairs. Learn cookie types: session, persistent, secure, and HttpOnly, and how they balance personalization with privacy.

Learn how http sessions transform stateless http into stateful interactions by using session IDs and cookies to track user data such as login status and shopping cart across requests.

Learn how a Python web app uses cookies and sessions to manage user signup, login, and dashboard access, with practical browser DevTools inspection.

Learn how RESTful APIs operate over HTTP, perform CRUD operations, and enable authentication and authorization, with versioning and cross-platform reuse across web and mobile apps using JSON.

Explore how APIs decouple large web applications, using HTTP status codes and REST APIs to manage get, post, put, and delete operations with headers and content negotiation, testing with Postman.

Learn how authentication verifies identity and authorization assigns roles to control access to protected API resources, using basic and token-based methods like JWT.

Explore API versioning in a Python app by demonstrating URL versioning, parameter versioning, header versioning, and resource URL versioning, with version 1 and version 2 responses in JSON.

Explore how http caching stores data in a cache to speed up web pages, reduce server load, and improve response times with ttl across cpu, web, and browser cache.

Explain how cache control headers guide browser and proxy caches to store or fetch resources using directives such as public, private, no-cache, and max-age. Utilize ETag for freshness checks.

Explore how cache validation checks whether cached resources are still valid using last-modified, if modified since, and etag with if none match, and how 304 not modified responses guide revalidation.

Explore what https is and how it secures data between your browser and the server using tls/ssl, public and private keys, and certificates from authorities, with browser indicators of security.

Explore http/2 and http/3, including multiplexing, header compression, and server push prioritization, alongside SSL and TLS, and certificates and authorities for secure web communications.

Explain how http vs https secures web communication using tls, public and private keys, and certificate authorities, including ssl certificates and the http/3 quic-based enhancements.

Reflect on the complete http course journey, from basics to advanced topics, covering requests and responses, headers, restful apis, security with https, and real-world python web examples.
