About

This package provides a example for the AsioHeaders package and its use from R via Rcpp. It serves as an illustration of a minimally viable package from which users derive their own extensions.

Example

The following code snippet shows two commands. First, we load the package. Second, we run the example from the help page of the httpClient(). In this example, httpClient() is called with the arguments for the Apache.org site, and the top-level (ascii and short) file robots.txt. The http client implemented here first shows all the relevant http headers, followed by the mere three lines of content.
