# HTTP Server Start

## Overview

![The HTTP Server Start Node.](/files/ACEJC8R2LOd7Z1v5uWrf)

The **HTTP Server Start Node** starts communication with a server that has already been set up in [**Project Settings**](/incari-studio/2022.2/modules/project-settings/http.md).

It is important to note that while the **HTTP Server Start Node** starts a connection to an **HTTP Server**, it may not completely finish establishing said server when the **Node** is executed. This could lead to the **Logic** attached to its **Output Pulse** to not work even though there is technically nothing wrong. In order to avoid this, it is highly suggested to use the [**On HTTP Server Start Node**](/incari-studio/2022.2/toolbox/communication/http/events/onhttpserverstart.md) instead. This way, the **Logic** will only execute once the **HTTP Server** connection has definitely been established.

Again, the user must first use the **HTTP Server Start Node** to open the connection. Separately, the **On HTTP Server Start Node** can be used to execute the desired **Communication Logic**.
