HTTP - User-agent

Let's intercept the request using Burpsuite so that we can modify it.

We can now send the request to Repeater.

User-Agent

The User-Agent request header is a characteristic string that lets servers and network peers identify the application, browser used to make the request.

We have to modify it to admin.
