I'm maintaining a rather old Web Forms application, which needs to move to a new Server.
The Server is up and running and when I deploy the Web Forms Project to wwwroot everything works fine under the Default Web Site.
I now wanted to replicate the setup of the old server, where we had the prod and test system running side-by-side in folders inside wwwroot (not the best idea, I know, but it worked so far and the client doesn't see the need of changing anything).
If I move the Web Forms Project to a subfolder in wwwroot, e.g. wwwroot/prod, go to IIS and change the prod folder to an application I can't access the page anymore (when navigating to localhost/prod).
In the logs I find the following:
#Software: Microsoft Internet Information Services 10.0
#Date: 2021-10-19 12:13:39
#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) cs(Referrer) sc-status sc-substatus sc-win32-status time-taken
2021-10-19 12:13:39 ::1 GET /prod - 80 - ::1 Mozilla/5.0+(Windows+NT+10.0;+WOW64;+Trident/7.0;+Touch;+rv:11.0)+like+Gecko - 301 0 0 12958
Does anybody have any idea what I need to add? The Web.config is the same as on the old server?
One difference that I've seen (apart from the IIS Version itself, old is 7 new is 10) is that the new one is missing the URL Rewrite Module.
Thanks in advance for any help, hope I'm in the right place here.
