django + session var not transferring between views

Once I submit my form in my home view we are redirected to my download view which has a false response for my session var... why??? I am unsure how to fix this issue and it feels like I've tried everything.

@login_required
def Home(request):
    form = TimeForm()
    search_times = []
    if request.method == "POST":

        # clear session data
        # for key in request.session.keys():
        #     test.append(request.session[key])

        start = request.POST['start_time']
        end = request.POST['end_time']
        start = time.mktime(datetime.datetime.strptime(start, "%Y-%m-%d %H:%M:%S").timetuple())
        end = time.mktime(datetime.datetime.strptime(end, "%Y-%m-%d %H:%M:%S").timetuple())


        start = re.split('.[0-9]+$', str(start))[0]
        end = re.split('.[0-9]+$', str(end))[0]
        search_times.append(int(start))
        search_times.append(int(end))

        request.session['search_times'] = search_times
        request.session.save()

    context = {
        'form': form,
        'search_times': search_times,
    }
    return render(request, "pcap_app/home.html", context)

def Download(request, path):
    test = []
    access_time = []
    search_times = []

    search_times = request.session.get('search_times', False)

    # testing timestamp directory listing
    files = sorted_ls(os.path.join(settings.MEDIA_ROOT, path))
    for f in files:
        time = os.stat(os.path.join(settings.MEDIA_ROOT, f)).st_mtime
        access_time.append(int(re.split('.[0-9]+$', str(time))[0]))

    context = {
        'sort': files,
        'times': access_time,
        'search': search_times,
        'test': test,
    }
    return render(request, "pcap_app/downloads.html", context)

home.html

<head>
    <script                    src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <link href="{{ STATIC_URL }}css/bootstrap.css" rel="stylesheet" type="text/css"/>
    <script src="{{ STATIC_URL }}js/bootstrap.js"></script>
    {{ form.media }}
</head>
<body>
    <h1>pcap search</h1>

    {% if user.is_authenticated %}

    <form  action="/download/" method="POST">
    {% csrf_token %}
    {{ form.as_p }}
    <input id="submit" type="submit" value="Submit">
    </form>
    {{ search_times }}
    {{ test }}
        <a href="/logout/">Logout</a>

    {% else %}
        <a href="/login/?next={{ request.path }}">Login</a>

    {% endif %}
</body>

You have wrongly set the action attribute in your home.html template as /download/.

When you submit the form, the POST request is submitted to the /download/ view and not the home view. So, the code for setting the session is never executed.

You need to change the action attribute to your home view url. When you do this, in case of POST requests, the variable search_times will be set in the session. 

 <form  action="/home/url/" method="POST">

After specifying the action attribute in home.html, you will need to redirect to /download/ in home view. Then after the redirection happens to your download view, you will be access the search_times vaiable in the session. 

@login_required
def Home(request):
    form = TimeForm()
    search_times = []
    if request.method == "POST":
        ...
        request.session['search_times'] = search_times # set the variable in the session
        return HttpResponseRedirect('/download/') # redirect to download page

    context = {
        'form': form,
        'search_times': search_times,
    }
    return render(request, "pcap_app/home.html", context)
