# HTTP Server Start

## Overview

![The HTTP Server Start Node.](https://2628349686-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fwnv17cpjDin2deSlOz0z%2Fuploads%2Fgit-blob-0946fb20cdae696683fb6d19276c6d4e1939b670%2Fhttpserverstartupdatedimage.png?alt=media)

The **HTTP Server Start Node** starts communication with a server that has already been set up in [**Project Settings**](https://docs.incari.com/incari-studio/2023.1/modules/project-settings/http).

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**](https://docs.incari.com/incari-studio/2023.1/toolbox/communication/http/events/onhttpserverstart) 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**.
