CA bundle over HTTPS May 8 2014

Our CA extract service is very popular to download Mozilla's CA cert bundle in PEM format. Starting now, we also provide a proper HTTPS download link for users who want to be sure there's no foul play going on during the download.

The HTTPS download is provided via github so it will also provide an alternative hosting site for cases where one or the other has problems. Since there's a chicken-and-egg problem with TLS and CA certs, we still offer the same download URL as before over plain HTTP as well.

Thank you for flying curl.

Brand new Development section October 9 2010

Starting now, we have Development section of this web site that is dedicated for all curl and libcurl hackers that work on improving our project.

As a consequence, we've also moved a bunch of pages into the dev section to make the "users" sections (for the curl tool and for libcurl) cleaner and more focused on what I suspect web users are looking for.

If you find errors or other things you think we should do to make this even better, just speak up!
