Redirecting url on computer?

Question

Browsers

There is a site example.com. he has different pages. example.com/asdf/
example.com/asdf/test
example.com/asdf/page.php
example.com/asdf/about.php I want to make on my machine so that when I type example.com the browser and all
other
programs on the computer meant this example.com/asdf/ . i.e. a kind of proxy with address spoofing. Can this be done quickly and easily?
Once again, I write example.com/ in the address bar, and the request goes to example.com/asdf/ . and when returning a response, as if it comes from example.com/
