I will give you an example;
first website: www.example.com --> it is .NET and IIS. second website: mywebsite.site.com --> it is PHP and Apache (or nginx or iis, nevermind)
I want to use "second website" as "www.example.com/myweb".
How can be it possible? Is that possible with some "web.config" configurations or more?
Not: iframe is not an option. It should work as subdirectory (and all of its subpages should work as www.example.com/myweb/first-page etc.) thats so important.
