What’s in the box

  • src/liblsquic – the library
  • bin – demo client and server programs
  • tests – unit tests


To build the library, follow instructions in the README file.

Demo Examples

Fetch Google home page:

./http_client -s -p / -o version=Q050

Run your own server (it does not touch the filesystem, don’t worry):

./http_server -c,fullchain.pem,privkey.pem -s

Grab a page from your server:

./http_client -H -s -p /

You can play with various options, of which there are many. Use the -h command-line flag to see them.
