问题
I am attempting to go to a HTTPS site from a WebBrowser Control in a Web Application, to get some basic information from the site (the site does not have a web service or any other API at this point) When I do this from IIS Express I am able to connect login and navigate to other pages just as I do when directly connecting from the web browser on that system everything works fine.
From most Development systems i.e. Windows 10 or Windows Server 2016 I can publish the web application, connect to the web application and then through the web application connect to the site, login and load other pages everything works fine. BUT…. When I deploy to GoDaddy and connect to the site through the application I am able to log in successfully but when I navigate to another page I am redirected to the login page.
I have noticed that I do not get back any JSESSION Cookies when going through the application on GoDaddy but I do get them in all of the other successful cases. I receive the JSESSON Cookies before I log in at the target site: http://www.altavista.com/ but any website that returns cookies on connect should suffice. I have changed the user agent to the same agent I have on the desktop and connected and still get the same results on GoDaddy.
I have tried this on GoDaddy sites that are SSL protected (HTTPS) and those that are not Just (HTTP). Hopefully someone has run into this type of problem before using the WebBrowser Control?
Here’s a test snippet of the code (As you might note I have tried lots of things to figure this out CookiePresistance, Clearing Cookies, JScript to clear the status etc.:

I found this post from 2006: http://www.tech-archive.net/Archive/InetSDK/microsoft.public.inetsdk.programming.webbrowser_ctl/2006-03/msg00073.html Apparently Cookies are not handled by the Security Manager they are handled by the Zone manager which cannot be customized. The only way to fix this is to add an additional zone for your specific needs to the registry. Unfortunately there is no way to do this from code when you are using the WebBrowser Control. And if your Site is Hosted in a Web Farm you don't have access to the registry so another approach will be needed (possibly a IE Plug In or deploy on a server where you have access and permission to set the default browser to what you need)
