Redirection in web development refers to the process of automatically forwarding a user from one URL to another. This can be useful for various reasons such as directing users from an old URL to a new one, handling temporary maintenance pages, or enforcing canonical URLs for SEO purposes.

There are different methods of redirection, but two common ones are:

HTTP Redirects (3xx status codes): This is a server-side redirection mechanism where the server sends a response to the client with an appropriate HTTP status code and a new URL to which the client should navigate.

Meta Refresh: This is a client-side redirection mechanism that involves embedding a meta tag in the HTML of a page, instructing the browser to automatically redirect to a different URL after a specified amount of time.

Here's how you can implement both methods:

HTTP Redirects
Using Python and Flask web framework:

python
Copy code
from flask import Flask, redirect, url_for

app = Flask(__name__)

@app.route('/')
def index():
return redirect(url_for('new_page'))

@app.route('/new_page')
def new_page():
return 'This is the new page!'

if _name_ == '__main__':
app.run()
In this example, accessing the root URL (/) will trigger a redirection to /new_page.

Meta Refresh
html

In this example, the browser will wait for 5 seconds (content="5) before automatically redirecting to https://example.com/new_page.

Both methods have their use cases and can be chosen depending on the specific requirements of your application.
