CORS error on same domain?

📝 Blog Post: CORS Error on the Same Domain? Here's How to Fix It! 🌐🛠️

Hey there, fellow tech enthusiasts! 👋 Have you ever encountered a frustrating CORS error while working on a web development project? 🤔 Well, fret not! Today, we're going to dig deep into this issue and provide you with some easy solutions. Let's get started! 💪

So, imagine this scenario: you have two servers, localhost:8666/routeREST/ and localhost:8080/, and you're experiencing a peculiar CORS problem. 🔄 The error message you're seeing goes something like this:

XMLHttpRequest cannot load http://localhost:8666/routeREST/select?q=[...] 
Origin http://localhost:8080 is not allowed by Access-Control-Allow-Origin

Let's break it down. 🧩 This error occurs when you're trying to make an XMLHttpRequest from one server (localhost:8080) to another (localhost:8666/routeREST/), and the server you're making the request to doesn't allow requests from the origin (localhost:8080).

Now, you might be wondering, "What's causing this CORS error?" 🤔 Well, in most cases, it's due to a missing or incorrect Access-Control-Allow-Origin header on the server you're making the request to. 🚫🌐

But fear not! Here's a simple solution to fix this CORS issue. 😄👍 If you're using a Python Bottle server like the one mentioned in the question, you can follow the steps outlined in this Stack Overflow post:
