Subsites do not inherit the parent's Webconfig

Environmental W10 iis10/win2012

There was previously a Web site on IIS, which later wrote an interface item that needs to be hooked up to this web site as a Web application.

After you right-click Add Application, point to interface item. The interface project is not reachable. There is a problem with the configuration.

Looking for a long time on the Internet, using a configuration specifies that subsites do not inherit the Webconfig configuration of the parent Web site

The test is feasible:

In the webconfig of the parent site, set a layer outside the <system.web> section

<location path= "." Allowoverride= "true" inheritinchildapplications= "false" >

<system.web>

....

</system.web>

</location>

This means that the subsite is not allowed to inherit this configuration

Tested. Subsites and main web sites can be opened without interference

In addition, there is no test method: Add <clear/> In the relevant configuration of the subsite

In the subsite, for example, this app profile section

<appSettings>
<clear/>//add a sentence, meaning not to inherit the original

...

</appSettings>
