Why Can\'t I Make HTTP Requests on the Go Playground?

HTTP Requests and the Go Playground

When attempting to utilize the provided example code for http.Get() at http://golang.org/pkg/net/http/#example_Get, you may encounter the following error:

2009/11/10 23:00:00 Get http://www.google.com/robots.txt: dial tcp: Protocol not available

Understanding the Error

This particular error message indicates that HTTP requests are not supported within the Go Playground. This is an intentional security measure implemented by the playground to prevent malicious or unauthorized network access.

Implications for Code

The reported error does not reflect an issue with your code. Instead, it is a limitation imposed by the Playground environment. HTTP requests can only be made when running your code outside of the Playground, such as on your local machine or a server.
