SP2013 : Alternate Acces Mapping not working on the entirety of the url

Question

I am missionned to go from HTTP to HTTPS on our SharePoint 2013 OnPremise farm.

This farm is made of several wfe (4 - including one for Workflows), 2 application servers and 2 sql instances. Users reach the SharePoint sites through a Proxy created mostly for Load Balancing (HaProxy).

I have installed everything (certificates, bindings, AAMs) as said in article Configure Alternate Mappings for SharePoint Server.

What is my problem :

I can reach my sites through https (by typing https://myWebApp.MyDomain.com/sites/MySite ),absolutely no issue there.

When trying to reach my site using http (http://myWebApp.MyDomain.com/sites/MySite), the redirection to https (https://myWebApp.MyDomain.com/sites/MySite/SitePages/Home.aspx) is working well.

When I try to directly access to my homepage via http - Which will be the case of all my user's bookmarks- (http://myWebApp.MyDomain.com/sites/MySite/SitePages/Home.aspx), The redirection to https does not work and the page is still in http.

Could you please help me resolve this strange case of strange behavior ? Rephrasing : Could you help me resolve this issue of partial redirection from http to https please ?

What I have done :

here are my configured AAMs :

Internal URL                     |   Zone     |  Public URL for Zone
https://MyWebApp.MyDomain.com    |   Default  |  https://MyWebApp.MyDomain.com
http://MyWebApp.MyDomain.com     |   Default  |  https://MyWebApp.MyDomain.com
https://MyWebApp                 |   Intranet |  https://MyWebApp  
http://MyWebApp                  |   Intranet |  https://MyWebApp                       

Here are my bindings on my WFE1 server,on myWebApp.MyDomain.com :

Type    |  Host Name  |  Port  |  IP Address     |  Binding Info
http    |             |  80    |                 |  
https   |             |  443   |   *             |     

The right certificate is associated to the https binding. (well, these work, because I can access my Site through typing a https URL.

Thanks a lot !!

The best option for you would be to set up the IIS URL Rewrite Module as explained in the article below- https://www.sharepointdiary.com/2015/02/redirect-http-to-https-in-sharepoint-2013.html

I have been using it in our Production environment and it is working just fine for me.
