Http dont load but Https works. Flask, Fastcgi, IIS

Question

I have a page public with Flask, using like handler Wfastcgi and IIS to compilate. The site works correctly using https but when i write the site with http that broke with timeout.

I tried changing in my index.py but didn't work, i used this:

@app.before_request
def bef():
    if not request.is_secure:
        url = request.url.replace('http://', 'https://', 1)
        code = 301
        return redirect(url, code=code)
        else pass

I tried too create a URL rewrite rule at IIS to redirect HTTP to HTTPS but didn't work.

Is like if the request never in by the HTTP port because i tried print with if not request.is_secure and never printed even "hello world". Maybe the mistake is produced for the wfastcgi because only is activated to HTTPS but i dont know who i could activate with HTTP, i searched in the file and saw this: record.params['wsgi.url_scheme'] = 'https' if record.params.get('HTTPS', '').lower() == 'on' else 'http'.

I add too the line handler in the web.config, maybe is wrong.

<add name="FlaskHandler" path="*" verb="*" modules="FastCgiModule" scriptProcessor="C:\Python\python.exe|C:\Python\Lib\site-packages\wfastcgi.py" resourceType="Unspecified" requireAccess="Script" />

Thanks for all
