A Modern and Flexible Web Client for R R package curl version 7.1.0 CRAN Task View: WebTechnologies (https://CRAN.R-project.org/view=WebTechnologies) Bindings to 'libcurl' <https://curl.se/libcurl/> for performing fully configurable HTTP/FTP requests where responses can be processed in memory, on disk, or streaming via the callback or connection interfaces. Some knowledge of 'libcurl' is recommended; for a more-user-friendly web client see the 'httr2' package which builds on this package with http specific tools and logic.
