Codex: What Are HTTP Headers?

After they came up on a call and I didn't understand what they were I was advised to go away and watch some videos about HTTP headers.

Now as you all know it is impossible for me to watch a video without writing notes on it so here we are. 

Btw "Codex" is a song by the PHENOMENON Joel Sunny, please expect many more posts named after his music.

What is a header in an HTTP request?

So according to Chat GPT (I watched one video and got lost but will try another in a sec), headers "tell the server" things like:
  • Your identity
  • The type of request you want
  • The format you want your response in
Except that because it's me I have got Chat GPT talking about magical kingdoms... of course, naturally.

Different types of headers

  • Request headers: Tell the server about you and your request
  • Response headers: Tell you how the server is responding

A beautiful picture of dragons with scales and a dragon egg. Text reads: Headers in HTTP requests ... with dragons

Omg so many dragons... in my analogy... yes yes yes thank you. Look: 

An example of a test with a dragon emoji explaining different types of headers

And it gets even better wait:

YouTube Video

I am watching a YouTube video, it is soooo good. I really really like this lady - she's  so niiiiiiiiiiiice. This lovely video explains that:
  • APIs are like information or knowledge transferred from one person to another inside of envelopes
  • Headers are like too and from addresses on an envelope - wow
  • Headers are like metadata for the content that is inside
  • It says there are two more types of headers than Chat GPT said - payload headers and representation headers
Apparently all headers are key value pairs...

I could've watched more but after 3 minutes I got the general idea that I needed so better to wrap up and go on lunch soon before my next meeting - especially as I have to ask Chat GPT one more thing about what my boss said later on - thanks.

Back to Joel Sunny, just for a minute

I just love his music videos. They are so beautiful. In fact I promised myself a re-watch of Luminary as a reward for watching a video.

Good thing it's lunchtime... 🫶 🥰 thank you for this beautiful and magical and lovely learning experience, I love learning so so so so much, thank you 🫶

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as

Yosemite

Yosemite I'll never forget the first time I head the song Yosemite by Lana del Rey. I very nearly clicked away.  It was quite near the start of my Software Engineering journey, right near when I start learning the Front-End/Web Development. I was listening to Arcadia by LDR before, maybe twice, and then Blue Banisters came on. I nearly clicked away in the first 30 seconds but I forced myself to keep listening anyway.  I'll never forget how that song has made me feel. It became my song of 2022 even though I only discovered it in November. I can still listen to it every day and get that complete sense of wonder and of awe that I felt the first time that I heard it. That ending of the song is completely amazing, and it just completely just blows me away every time. "Withstanding all the time, changes, and seasons..." - LDR Concise Body Arrow Functions Why am I so bad at arrow functions? Whyyyyyyyyyyy?  Just kidding, I am beginning to get them. But why are they so hard? &

Two Lines of Thought, Makes Me Wonder What I'm Missing

Two Lines of Thought, Makes Me Wonder What I'm Missing "Lines of Bamboo, See What You Do To Me..." Bamboo by Elder Island is one of my ultimate 'becoming a Software Engineer songs'. (I prefer the original, but here is a great live version. ) There's a story behind this. I met a man named Mark. He was an SWE approaching retirement - he was down in my hometown with his wife, visiting. I won't go into the context of how we met, but it was a miracle. It was a complete miracle. It was just meant to be. We chatted for at least two hours and at the end of the conversation he said to me "All the best of luck with your new career". I couldn't believe what he'd just said - I hadn't even committed to it yet! A few weeks later, I did, though. After I walked out of that cafe where I had been sitting and talking to Mark and his wife though, I felt like - even though I didn't "feel ready" yet - Mark had predicted something that I didn&
