Understanding HTTP Request Methods & Verbs
Introduction
Ever wondered how your favorite apps and websites talk to servers behind the scenes? Enter HTTP request methods – the unsung heroes of the internet! These nifty little commands are like the secret language that web browsers and servers use to chat with each other.
Think of HTTP methods as different ways to knock on a server's door. Sometimes you're just asking for information (like when you're window shopping online), and other times you're sending data (like when you're filling out a form). Each method has its own special way of doing things.
Why should you care about these technical-sounding terms? Well, if you're a web developer or aspiring to be one, understanding HTTP methods is like learning the ABCs of web communication. It's the foundation for building robust and efficient web applications and RESTful APIs – the backbone of modern web services.
But don't worry if you're not a tech wizard! Even if you're just curious about how the web works, getting to know these methods will give you a cool behind-the-scenes look at the internet magic happening every time you click a button or load a page.
In this blog post, we'll break down the most common HTTP methods in plain English. We'll explore what they do, when to use them, and why they're important. By the end, you'll have a solid grasp of these essential web building blocks – and maybe even impress your tech-savvy friends at your next trivia night!
What Are HTTP Verbs, Anyway?
When you hear people talk about “HTTP verbs,” they’re really just talking about the different actions your browser can take when talking to a server. These “verbs” aren’t just fancy grammar—they’re the instructions that let the web know exactly what you want to do. For example, do you want to fetch info, send new data, update something, or maybe delete it altogether? Each verb, like GET, POST, PUT, or DELETE, tells the server what kind of move you’re making.
In simple terms, HTTP verbs are the action words of web communication—they set the tone for every request and response between your browser and the websites you visit.

Less Common HTTP Methods
Now that we've covered the all-stars of HTTP methods, let's take a quick tour of some of the backup dancers. These methods might not get as much spotlight, but they've got some pretty cool moves of their own!
HEAD: The Peek-a-Boo Player
Imagine if you could check what's inside a gift-wrapped present without actually opening it. That's basically what HEAD does! It fetches all the metadata about a resource without actually downloading the resource itself. Super handy when you just want to know things like file size or when a webpage was last updated.
Purpose: HEAD is like peeking through the wrapper without opening the gift. When you use HEAD, you're asking the server for all the headers (like size, content type, and last updated date) you’d get with a GET request, but without downloading the actual data itself.
Why use it? It's perfect when you want to check if a file exists, see when something was last updated, or get info about what you're about to download—without using up bandwidth on the full content. Think of it as glancing at the nutrition label before buying your favorite snack. You get all the details, but you haven’t actually taken a bite!
OPTIONS: The Friendly Doorman
OPTIONS is like the helpful concierge at a fancy hotel. It tells you what you're allowed to do with a particular resource. Want to know if you can POST to a certain URL? OPTIONS will give you the lowdown on which HTTP methods are welcome at that particular address.
TRACE: The Echo Chamber
TRACE is the diagnostic tool of HTTP methods. It's like shouting "Echo!" in a cave – it sends a message to the server and then returns exactly what it received. This can be super useful for debugging, especially when you're trying to figure out if any intermediate servers are messing with your requests.
CONNECT: The Secret Tunnel Builder
Last but not least, we have CONNECT. This method is a bit of a special case, mostly used for setting up secure connections through proxy servers. Think of it as digging a secret tunnel to your destination when you can't just walk straight there. It's not something you'll use every day, but it's crucial for certain security scenarios.
And there you have it – the supporting cast of HTTP methods! While you might not use these as often as their more famous cousins (GET, POST, etc.), knowing they exist can make you feel like a true HTTP methods maestro. Plus, you never know when one of these might save the day in a tricky development situation!
Purpose: CONNECT is like the master of disguise in the HTTP world. Its main job is to create a secure tunnel between your browser and another server, often used when you need to set up an encrypted (HTTPS) connection via a proxy.
How does it work? Imagine you're at a crowded party (the internet), but you want to have a private conversation (secure connection) with your friend (the destination server). You ask the host (the proxy server) to set up a secret tunnel just for you two. Once the tunnel is in place, your messages travel directly through it, safe from prying eyes.
CONNECT is mostly used behind-the-scenes by browsers, VPNs, and tools like Postman when you access secure sites. Most everyday users never interact directly with CONNECT, but it plays a vital role in keeping online communications safe and private.

Safety and Idempotency
Alright, let's dive into the world of safety and idempotency. Don't worry, we're not going to get too technical here. Think of these as the personality traits of our HTTP method friends!
Safe vs. Unsafe Methods: The "Look, Don't Touch" Rule
Safe methods are like well-behaved museum visitors. They look at the exhibits (or in our case, server resources) but don't touch or change anything. GET and HEAD are prime examples of safe methods. They're all about retrieving information without altering the server's state.
Unsafe methods, on the other hand, are like the interactive exhibits at a science museum. They can potentially change things on the server. POST, PUT, DELETE, and PATCH fall into this category. When you use these, you're telling the server, "Hey, I want to make some changes around here!"
Idempotent vs. Non-Idempotent Methods: The "Repeatable" Factor
Now, let's talk about idempotency. Imagine pressing an elevator button. Whether you press it once or a hundred times, the result is the same – the elevator comes to your floor. That's idempotency in action!
Idempotent methods in HTTP work similarly. You can repeat them multiple times, and the end result will be the same as if you'd only done it once. GET, PUT, DELETE, and HEAD are idempotent. For example, if you DELETE a resource and then try to DELETE it again, the end result is the same – the resource is gone.
Non-idempotent methods, like POST, are more like playing a slot machine. Each time you pull the lever (or in this case, send a request), you might get a different result.
Here's a handy table to summarize the safety and idempotency of common HTTP methods:

HTTP Methods in RESTful API Design
Related Topics: Beyond the Methods
Just when you thought you’d mastered the HTTP methods, there’s more to the story! To truly understand what's happening behind the curtain of your web browser, it's worth getting familiar with a couple of other key players:
HTTP Response Status Codes: These are the server’s way of giving you a thumbs-up, a shrug, or a digital frown. Ever seen a “404 Not Found” error? That’s a status code! They tell you if your request was successful, redirected, blocked, or if something went hilariously wrong (looking at you, 418: I’m a teapot).
HTTP Headers: If the methods are the action and the status codes are the verdict, headers are the fine print. Headers carry extra details about the request and response—like what type of data is being sent, how long to keep it around, or special instructions for browsers. It’s like sending a letter with sticky notes attached for the mail carrier!
Exploring these topics will help round out your understanding of how the web seamlessly connects users, browsers, and servers every moment of the day.
And there you have it – a whirlwind tour of HTTP methods! From the common GET and POST to the less-known HEAD and OPTIONS, these methods are the secret sauce that makes the web work. Understanding them is key to building efficient, well-designed web applications and APIs.
Remember, each method has its own superpower, whether it's safely fetching data or efficiently updating resources. By choosing the right method for each task, you're not just following best practices – you're speaking the language of the web fluently.
So next time you click a button or submit a form online, you'll know exactly what's happening behind the scenes.
