Multiscrape with form and cookies

Hi
I try to get the timetable from my daughters school.
When i supply the multiscraper with a link which i clicked before on my pc all is working, but if i try to get it working with a resource_template then i get always the same data. i wanted to try to get data from this week and next week so i have to change the dates. When i do this in my browser address row it works. but i dont know how to get it working with multiscrape.

  - name: Stundenplan
    resource_template: "https://ge-hsw.de/iserv/auth/login?_target_path=/iserv/auth/auth?_iserv_app_url%3D%252Fiserv%252Ftimetable%252Fdata%253Ffilter%253D%25257B%252522startDate%252522%25253A%252522{{ states('sensor.monday') }}%252522%25252C%252522endDate%252522%25253A%252522{{ states('sensor.friday') }}%252522%25252C%252522classes%252522%25253A%25255B%25252208a%252522%25255D%25252C%252522teachers%252522%25253A%25255B%252522%252525%252522%25255D%25252C%252522rooms%252522%25253A%25255B%252522%252525%252522%25255D%25252C%252522child%252522%25253Anull%25257D%26client_id%3D92_i8fni3gyp9ckw8sgw844owocgw8wso00gkgo0wocwcw4sg4ss%26nonce%3D60886da1-c85f-4a8e-a459-0df1a0fc1dee%26redirect_uri%3Dhttps%253A%252F%252Fge-hsw.de%252Fiserv%252Fapp%252Fauthentication%252Fredirect%26response_type%3Dcode%26scope%3Dopenid%2520uuid%2520iserv%253Asession-id%2520iserv%253Aweb-ui%2520iserv%253A2fa%253Aconfiguration%2520iserv%253Aaccess-groups%26state%3DeyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiIsImtpZCI6IjEifQ.eyJyZWRpcmVjdF91cmkiOiJodHRwczpcL1wvZ2UtaHN3LmRlXC9pc2VydlwvdGltZXRhYmxlXC9kYXRhP2ZpbHRlcj0lN0IlMjJzdGFydERhdGUlMjIlM0ElMjIxOC4wOS4yMDIzJTIyJTJDJTIyZW5kRGF0ZSUyMiUzQSUyMjI0LjA5LjIwMjMlMjIlMkMlMjJjbGFzc2VzJTIyJTNBJTVCJTIyMDhhJTIyJTVEJTJDJTIydGVhY2hlcnMlMjIlM0ElNUIlMjIlMjUlMjIlNUQlMkMlMjJyb29tcyUyMiUzQSU1QiUyMiUyNSUyMiU1RCUyQyUyMmNoaWxkJTIyJTNBbnVsbCU3RCIsIm5vbmNlIjoiNjA4ODZkYTEtYzg1Zi00YThlLWE0NTktMGRmMWEwZmMxZGVlIiwiYWRtaW4iOmZhbHNlLCJpc3MiOiJodHRwczpcL1wvZ2UtaHN3LmRlXC9pc2VydlwvIiwiZXhwIjoxNzAzMDg4MjYzLCJuYmYiOjE2OTUzMTIyMDMsImlhdCI6MTY5NTMxMjI2Mywic2lkIjoiIn0.vE0PHQdpBxG_p3ZeVOt-PvnSJmBS0WAeNMWX0iDEjpBijFZ6OAAXjiIx7dOWXTWHgchOMIvodjSj9uRmJgp_Yw"

    sensor:

this is what i have. whith this i can get the current data. but if i change the date in my sensors the debug log will show the correct address but the data is i get is not changed.
Probably because of the cookies i get, when i go to the page.
But i dont know how to get the cooking from the login page and use it while login will send.

any news on that (gerne auf deutsch)?

nein aber meine Tochter hat jetzt nen neues Schuljahr angefangen und da werd ich die Tage noch mal rein schauen

I just released Multiscrape v7.1.2 with suppport for cookies!

is it working? I am trying to grab “Infobildschirm” and Klausuren
