asp.net - WebBrowser control in web server not returning Cookie from Website -
i attempting go https site webbrowser control in web application, basic information site (the site not have web service or other api @ point) when iis express able connect login , navigate other pages when directly connecting web browser on system works fine.
from development systems i.e. windows 10 or windows server 2016 can publish web application, connect web application , through web application connect site, login , load other pages works fine. but…. when deploy godaddy , connect site through application able log in when navigate page redirected login page.
i have noticed not jsession cookies when going through application on godaddy them in of other successful cases. receive jsesson cookies before log in @ target site: http://www.altavista.com/ website returns cookies on connect should suffice. have changed user agent same agent have on desktop , connected , still same results on godaddy.
i have tried on godaddy sites ssl protected (https) , not (http). has run type of problem before using webbrowser control?
here’s test snippet of code (as might note have tried lots of things figure out cookiepresistance, clearing cookies, jscript clear status etc.:

} } i found post 2006: http://www.tech-archive.net/archive/inetsdk/microsoft.public.inetsdk.programming.webbrowser_ctl/2006-03/msg00073.html apparently cookies not handled security manager handled zone manager cannot customized. way fix add additional zone specific needs registry. unfortunately there no way code when using webbrowser control. , if site hosted in web farm don't have access registry approach needed (possibly ie plug in or deploy on server have access , permission set default browser need)
