Restricting access from overseas
Estimated time: 5 minutes
Overview
This tutorial explains how to restrict access to a website from overseas using KurocoEdge.
In this exercise, we will be setting up rules in KurocoEdge to restrict the access of the website to only allow traffic from USA or restricting access from specific countries.
Prerequisites
This tutorial assumes that you have completed the following tutorials in the Beginner's Guide.
What You'll Learn
You will learn how to control the display based on the country of origin using the following steps:

Creating rules
Click on [KurocoEdge] > [Deployment list] in the side menu.
Select the draft deployment.
Click on [Clone] in the top right corner.
As the default backend, set your own site's URL which you added in Changing the Display of Your Website.
Click on [Add] in the rule list section.
Click on the "Request" tab.
Click on [Add Action].
Condition / Variable
