# 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 <loglevel>|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.
|
|
|
|
```
|
|
$ ./lws-minimal-http-client-custom-headers
|

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
|
|
|
|
