Python Flask is a popular web application framework known for its simplicity and flexibility. When it comes to deploying Flask apps, cPanel is a powerful hosting platform that offers a lot of flexibility for setting up and managing web applications. In this article, we will be exploring the Python Flask app routing specific to cPanel, but with a catch – our routing will be limited to the root URL.Routing is an essential part of any web application as it is responsible for directing user requests to the relevant parts of the application. Flask has a robust routing system that allows developers to define URL patterns and associate them with specific functions. This makes it easy to create complex web applications with many different routes that can handle various types of user input.However, when it comes to cPanel, the routing system is slightly different. While Flask’s default routing system allows for any level of nesting and complexity, cPanel limits the routing to the root URL only. This means that all requests to your Flask application will have to be directed through the root URL, which can be challenging if you have a complex application structure.In this article, we will be discussing how to set up a Flask application using cPanel, including how to configure the routing of your application to work within the limitations of the cPanel hosting environment. We will also discuss best practices for working with Flask and cPanel, including tips for optimizing performance and ensuring the security of your web application. So, whether you’re a seasoned Flask developer or just getting started with web development, read on to learn how to get the most out of Flask on cPanel.

Comparison Blog Article: Python Flask App Routing in cPanel: Limited to Root URL
Introduction
If you’re a web developer who has used Python Flask, you know how great it is for building web applications in Python. But if you use cPanel as your hosting platform, you may have noticed that Flask app routing is limited to the root URL. This can be a frustrating limitation, especially if you need your app to support multiple routes.
What is Flask?
Before we dive into the limitations of Flask app routing in cPanel, it’s important to understand what Flask is and why it’s such a popular web framework. Flask is a micro web framework written in Python. It’s designed to be lightweight, modular, and easy to use, making it a great choice for building web applications in Python.
The Routing Limitation
The biggest limitation of Flask app routing in cPanel is that it’s limited to the root URL. This means that all requests to your Flask app must be handled by a single function. For example, if your Flask app is running at example.com, all requests, including example.com/login, example.com/signup, and example.com/about, must be handled by a single function.
The Workaround
While the limitation of Flask app routing in cPanel may seem like a major roadblock, there is a workaround that can be used to get around this limitation. The workaround involves using a PHP script as a gateway to your Flask app. The PHP script is called whenever a request is made to your Flask app, and the PHP script then forwards the request to the appropriate Flask function.
How to Implement the Workaround
To implement the workaround for Flask app routing in cPanel, follow these steps:
- Create a new subdirectory in your public_html directory called python.
- Upload a PHP script called proxy.php to the python subdirectory.
- Add the following code to proxy.php:
Code for Proxy.php
<?php
$script_name = dirname($_SERVER[‘SCRIPT_NAME’]);
$request_uri = $_SERVER[‘REQUEST_URI’];
$url = substr($request_uri, strlen($script_name));
$url = rtrim($url, ‘/’);
define(‘WSGI_SCRIPT’, ‘app.wsgi’);
define(‘WSGI_PATH’, ‘/home/username/public_html/python’);
exec(‘python ‘ . WSGI_PATH . ‘/’ . WSGI_SCRIPT . ‘ ‘ . $url);
?>
- Create a file called app.wsgi in the python subdirectory.
- Add the following code to app.wsgi:
Code for App.wsgi
from flask import Flask
app = Flask(__name__)
@app.route(‘/login’)
def login():
return ‘This is the login page.’
@app.route(‘/signup’)
def signup():
return ‘This is the signup page.’
@app.route(‘/about’)
def about():
return ‘This is the about page.’
if __name__ == ‘__main__’:
app.run()
- Modify the code in app.wsgi to include the routes that you need for your web application.
- Upload your Flask application to the python subdirectory.

| Flask App Routing in cPanel: Limited to Root URL | Workaround using PHP script as a gateway to Flask app |
|---|---|
| All requests must be handled by a single function | Requests can be handled by separate Flask functions |
| Not ideal for complex applications with multiple routes | Can handle complex applications with multiple routes |
| Limits flexibility and customization | Allows for greater flexibility and customization |
Opinion
While the workaround for Flask app routing in cPanel may seem like an annoying extra step, it’s actually a great solution. Using a PHP script as a gateway to your Flask app allows you to have greater control and flexibility over how your web application handles requests. Additionally, the workaround is relatively easy to set up, even if you’re not an experienced web developer.
Conclusion
Although Flask app routing in cPanel is limited to the root URL, there is a simple workaround that can be used to get around this limitation. By using a PHP script as a gateway to your Flask app, you can handle requests for multiple routes and create more complex web applications. While the workaround may seem like an extra step, it’s actually a great solution that allows you to customize and control your web application in a more granular way.
Thank you for taking the time to read our article on Python Flask App Routing in cPanel. We hope that you have found the information provided useful and informative. In this post, we discussed how to route your Flask app on cPanel, but with some limitations that restrict the routing only to the root URL.
This limitation may seem restrictive at first, but it can actually be beneficial in some cases. It allows you to create a simple, yet effective website or web application without the need for complex routing schemes. This can be particularly useful if you are just starting out in developing web applications, as it allows you to focus on the core functionality of your project without getting bogged down in the details of routing.
But for those who require more complex routing schemes, don’t worry! There are other options available. If you need to create pages that are not on the root URL, you can use the Flask Blueprints feature or look for a web hosting provider that offers more flexibility with regards to routing.
In summary, Python Flask App Routing in cPanel is a great way to get started with developing web applications, especially for those who are new to the world of web development. While the current limitations of routing may seem restrictive, they can be helpful for keeping things simple and focused. So go ahead and try it out!
