Redirecting an old URL to a new one with Flask micro-framework

Question

Hi,

I'm making a new website to replace a current one, using Flask micro-framework (based on Werkzeug) which uses Python (2.6 in my case).

The core functionality and many pages are the same. However by using Flask many of the previous URLs are different to the old ones.

I need a way to somehow store the each of the old URLs and the new URL, so that if a user types in an old URL they are simply forwarded to the new URL and everything works fine for them.

Does anybody know if this is possible in Flask?

Thank you in advance for your help :-)

Something like this should get you started:

from flask import Flask, redirect, request

app = Flask(__name__)

redirect_urls = {
    'http://example.com/old/': 'http://example.com/new/',
    ...
}

def redirect_url():
    return redirect(redirect_urls[request.url], 301)

for url in redirect_urls:
    app.add_url_rule(url, url, redirect_url)
