IIS 重写根目录下的 ARR 子文件夹和主站点 URL

Question

I might just be missing something small.

I have several sites that I have set up with ARR and they work except for the base URL which should still continue to point to the legacy app.

It should resolve to the following:

• www.mysite.com/app1 --> App1
• www.mysite.com/app2 --> App2
• www.mysite.com/ --> Legacy App ( Not working )

I understand that the rewrite rules are check in the order that it is placed, therefore I placed the legacy app last. I figure my matching URL regex is suspect.

Is this even possible? Would appreciate the help so much.

It seems that when you request url www.mysite.com/ , it is considered as directory, so it doesn't match the condition <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> .

If there aren't any directories when your application running, I think you can remove the second condition <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> in " Reverse Proxy to Legacy App " rule directly. And then it can implement your requirement.
