In essence, Burp Suite Repeater enables us to modify and resend intercepted requests to a target of our choosing. It allows us to take requests captured in the Burp Proxy and manipulate them, sending them repeatedly as needed. Alternatively, we can manually create requests from scratch, similar to using a command-line tool like cURL.
The ability to edit and resend requests multiple times makes Repeater invaluable for manual exploration and testing of endpoints. It provides a user-friendly graphical interface for crafting request payloads and offers various views of the response, including a rendering engine for a graphical representation.
The Repeater interface consists of six main sections, as depicted in the annotated diagram below:

Request List: Located at the top left of the tab, it displays the list of Repeater requests. Multiple requests can be managed simultaneously, and each new request sent to Repeater will appear here.
Request Controls: Positioned directly beneath the request list, these controls allow us to send a request, cancel a hanging request, and navigate through the request history.
Request and Response View: Occupying the majority of the interface, this section displays the Request and Response views. We can edit the request in the Request view and then forward it, while the corresponding response will be shown in the Response view.
Layout Options: Located at the top-right of the Request/Response view, these options enable us to customize the layout of the Request and Response views. The default setting is a side-by-side (horizontal) layout, but we can also choose a vertical layout or combine them in separate tabs.
Inspector: Positioned on the right-hand side, the Inspector allows us to analyze and modify requests in a more intuitive manner than using the raw editor. We will explore this feature in a later task.
Target: Situated above the Inspector, the Target field specifies the IP address or domain to which the requests are sent. When requests are sent to Repeater from other Burp Suite components, this field is automatically populated.
