In this guide, we will create an account on PythonAnywhere - a free Python hosting platform.

We will use it this platform to host a simple Python app that will help in the SSRF lab.

It should take few minutes, let's get started.

---------------------------------------

Step 1: Create Your Account

- Go to pythonanywhere.com

- Create a free account (Beginner account is sufficient)

- Verify your email

---------------------------------------

Step 2: Create a Web App

- Once logged in, go to the "Web" tab

- Click "Add a new web app"

- Click "Next" on the domain name screen (you'll get yourusername.pythonanywhere.com)

- Select "Flask" as the framework

- Choose Python 3.10 or latest available

- Keep the default path and click "Next"

---------------------------------------

Step 3: Replace the Default Code

Navigate to the "Files" tab.

Open: /home/yourusername/mysite/flask_app.py

Delete everything and paste this code:

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def redirect_to_localhost():
    """Redirect all requests to internal endpoints"""
    return redirect('http://localhost:8080', code=302)

if __name__ == '__main__':
    app.run()

Click "Save" (or Ctrl+S).

---------------------------------------

Step 4: Reload Your App

- Go back to the "Web" tab

- Find the green "Reload" button

- Click it to restart your app

Your app is now live at:

https://yourusername.pythonanywhere.com

---------------------------------------

Step 5: Test the Redirect

Open your browser and visit your app URL.

Notice what happens - the redirect to localhost:8080.

see you in the next lecture.
