# Simple HTTP web server
## Concepts
- Use the std library [http module](https://deno.land/std@$STD_VERSION/http) to
run your own web server.
## Overview
With just a few lines of code you can run your own http web server with control
over the response status, request headers and more.
## Sample web server
In this example, the user-agent of the client is returned to the client:
```typescript
/**
* webserver.ts
*/
import { serve } from "https://deno.land/std@$STD_VERSION/http/server.ts";
const server = serve({ hostname: "0.0.0.0", port: 8080 });
console.log(`HTTP webserver running. Access it at: http://localhost:8080/`);
for await (const request of server) {
let bodyContent = "Your user-agent is:\n\n";
bodyContent += request.headers.get("user-agent") || "Unknown";
request.respond({ status: 200, body: bodyContent });
}
```
Run this with:
```shell
deno run --allow-net webserver.ts
```
