History

Andy Green 498a4e2bd7 sul: all timed objects use a single pt sul list wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer all now participate on a single sorted us list. The whole idea of polling wakes is thrown out, poll waits ignore the timeout field and always use infinite timeouts. Introduce a public api that can schedule its own callback from the event loop with us resolution (usually ms is all the platform can do). Upgrade timeouts and sequencer timeouts to also be able to use us resolution. Introduce a prepared fakewsi in the pt, so we don't have to allocate one on the heap when we need it. Directly handle vh-protocol timer if LWS_MAX_SMP == 1		2019-08-09 10:12:09 +01:00

lws minimal http client custom headers

This http client application shows how to send and receive custom headers.

This currently only works on http 1, so the app forces that even if h2 enables.

build

 $ cmake . && make

usage

Commandline option	Meaning
-d	Debug verbosity in decimal, eg, -d15
-l	Connect to https://localhost:7681 and accept selfsigned cert
-n	no TLS

The app looks for a custom header "test-custom-header" sent by warmcat.com.

You can use the -n and -l to make this test app connect to localhost:7681 over http, and confirm the "dnt:1" header was sent either by tcpdump or by running the test server on :7681 with -d1151
