2024-02-06Add a wasi-http 0.2.0 echo-request component in CAndrew Clayton1-0/+0

2023-12-01wasi-http/echo-request: Simplify a littleAndrew Clayton1-15/+9
Use the 'blocking' versions of the stream read/write functions. Things seemed to work fine previously. However with a version of this that works under the enw Unit wasm module, it didn't and I needed to use the _input_stream_blocking_read() & _output_stream_blocking_write_and_flush() functions. The latter does also allow for a little less code. Let's also use those functions here... Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
