Here is how a request works, the main methods, and status codes.","category":"code","date":"May 13, 2026","author":"ByteLedger Team","content":"<span class=\"dropcap\">H</span>TTP, the HyperText Transfer Protocol, is the set of rules browsers and servers use to request and send web pages and data. When you open a page, your browser sends an HTTP request to a server, and the server sends back an HTTP response containing the page or data. Every click, image load, and API call on the web follows this same request-then-response pattern. It is the language the web speaks. This explainer covers how a request works, the main methods, what status codes mean, and how HTTP relates to HTTPS.\n\n## How an HTTP exchange works\n\nAn HTTP exchange has two halves. The client sends a request that names a method (what it wants to do), a URL (what resource), headers (extra information like the content type), and sometimes a body (data being sent). The server processes it and returns a response with a status code (what happened), its own headers, and usually a body (the page or data). Before any of this, the browser uses [DNS to resolve the domain name](/blog/what-is-dns-2026) into the server address it connects to.\n\n## HTTP methods\n\n| Method | Intent | Typical use |\n| --- | --- | --- |\n| GET | Read data | Load a page or fetch a record |\n| POST | Create or submit | Submit a form, create a record |\n| PUT | Replace | Update an entire resource |\n| PATCH | Modify partly | Update some fields |\n| DELETE | Remove | Delete a resource |\n\nThese methods are the backbone of how web APIs are designed. A well-built [REST API](/blog/what-is-a-rest-api-2026) maps these methods onto reading and changing resources in a predictable way.\n\n## HTTP status codes\n\nThe server answers every request with a three-digit status code, and the first digit tells you the category:\n\n```\n// status code families at a glance\n2xx -- success (200 OK, 201 Created)\n3xx -- redirect (301 Moved, 304 Not Modified)\n4xx -- client error (404 Not Found, 403 Forbidden)\n5xx -- server error (500 Internal, 503 Unavailable)\n```\n\nWhen something breaks, the status code is your first clue. A 4xx means your request was wrong; a 5xx means the server failed. Learning the common ones saves hours of guessing.\n\n## How to think about it\n\n1. **Picture the round trip.** Client requests, server responds, every single time.\n2. **Match method to intent.** Use GET to read and POST to create rather than overloading one method.\n3. **Read the status code first.** It narrows a problem to client side or server side instantly.\n4. **Notice headers.** Content type, caching, and authentication all ride in headers.\n5. **Move to HTTPS for anything real.** Plain HTTP sends data in the clear.\n\n## What to skip\n\n- **Do not obsess over protocol versions early.** Understand the request-response model before HTTP/2 and HTTP/3 details.\n- **Do not send sensitive data over plain HTTP.** It is unencrypted; use HTTPS.\n- **Do not misuse GET for changes.** GET should read, not create or modify, or caching and crawlers will surprise you.\n- **Do not ignore status codes in your own APIs.** Returning the right code makes clients far easier to build.\n\n## FAQ\n\n**What does HTTP stand for?**\nHyperText Transfer Protocol. It is the rule set that browsers and servers use to exchange web pages and data through requests and responses.\n\n**What is the difference between HTTP and HTTPS?**\nHTTPS is HTTP with encryption added, so the data exchanged cannot be read or tampered with in transit. Modern sites should use HTTPS.\n\n**What does a 404 mean?**\nIt is an HTTP status code meaning the requested resource was not found on the server. It is a client-side category error, the 4xx family.\n\n**Is HTTP only for web pages?**\nNo. It also carries API data, images, scripts, and more. Many applications talk to servers over HTTP without ever showing a traditional web page.\n\n## Where to go next\n\n[Add encryption with what HTTPS is](/blog/what-is-https-2026), [see how names resolve before a request with DNS](/blog/what-is-dns-2026), and [learn how APIs use HTTP methods in what a REST API is](/blog/what-is-a-rest-api-2026).","hue":200,"metaTitle":"What Is HTTP in 2026?
