add requestTimeout in web.config

Hello,

I am working on an ASP.Net Core 2.0 MVC web application.

When i type "dotnet publish", a web.config file is generated.

I wanted to add a parameter in this file (requestTimeout). It works fine but i this web.config is overwritten each time i publish my application.

Is there another file where i can change this value in my project in order to have the good requestTimeout value in the generated web.config when i publish my app.

Thanks
