Hi,

I'm trying to install Umbraco v7.4.3 on a server, on subfolder configured as virtual app, and when accessing the site to launch the installer, on Chrome I get a sort of infinite loop redirect that ends with a 404.

If I launch the same on IE the redirect works fine stopping after few redirects:

http://locapp-t-web1:985/pressinfo/install/?redir=true&url=http%3a%2f%2flocapp-t-web1%3a985%2fpressinfo%2flogin.aspx%3fReturnUrl%3d%252fpressinfo%252f#?redir=true&url=http:%2F%2Flocapp-t-web1:985%2Fpressinfo%2Flogin.aspx%3FReturnUrl%3D%252fpressinfo%252f

I never had such problem when installing Umbraco in the root node of the domain or running on my dev box.

Then I managed to install all using IE and now I've the same problem when trying to connect to the backoffice:

if I type http://locapp-t-web1:985/pressinfo/umbraco I get redirected to http://locapp-t-web1:985/pressinfo/login.aspx?ReturnUrl=%2fpressinfo%2fumbraco while in IE the umbraco page gets executed and loads angular views and so on.

Bug? Misconfiguration of IIS?

Any advice?

Thx Simone
