我怎样才能强迫匿名用户停留在一个页面上，一直把他重定向到那个页面，直到他在那里得到正确的验证码？为了处理验证码表单，我可以使用django simple captcha，我的问题是如何知道验证码是否被解决，如果没有，我如何重定向他。
confirmation.html

{% extends 'base/base.html' %}
{% block content %}
<div class="content">
    <h2 class="title">Captcha test.</h2>
    <form method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        {{ form }}
        <div>
            <button type="submit">Update</button>
        </div>
    </form>
</div>
{% endblock %}

forms.py

from django import forms
from captcha.fields import CaptchaField

class ConfirmationForm(forms.Form):
    captcha = CaptchaField()
    class Meta():
        fields = ['captcha']

    def save(self):
        # some type of anonymous user confirmation variable that I could set to true to stop redirecting the user
        anonymous.human = True

urls.py

from django.urls import path
from home.views import Confirmation, Home

urlpatterns = [
    path('', Confirmation, name='confirmation'),
    path('', Home, name='home'),
]

views.py

def Confirmation(request):
    if request.method == 'POST':
        if anonymous.human == True:
            return redirect('home')
        if anonymous.human == False:
            return redirect('confirmation')
    else:
        form = ConfirmationForm()

    context = {
        'form': form,
    }

    return render(request, 'base/confirmation.html', context)


def Home(request):
    if human == False:
        return redirect('confirmation')

    context = {
        ...
    }

    return render(request, 'base/home.html', context)
