## What it is
A Lua HTTP client cosocket driver for OpenResty / ngx_lua, supporting HTTP 1.0/1.1, SSL, streaming response bodies, keepalives, and request pipelining. It is production ready and distributed via LuaRocks.

## Use cases
- make HTTP requests from OpenResty Lua code
- stream large HTTP response bodies with predictable memory usage
- pipeline multiple HTTP requests over a single connection
- reuse keepalive connections to upstream services in nginx
- make mTLS requests from ngx_lua
- propagate W3C trace context headers in outbound requests

## When to choose
- you are building services on OpenResty or ngx_lua and need an HTTP client
- you need streaming or pipelined HTTP requests with low memory overhead
- you want connection keepalive pooling to upstream APIs

## When to avoid
- you are not running OpenResty / ngx_lua (e.g. plain Lua or other web servers)
- you need HTTP/2 support
- you want a high-level REST client with retries and middleware out of the box

## Facets
- artifact type: library
- maturity: stable
- function: http-client, streaming, middleware
- domain: web-development, backend, apis, developer-tools
- platform: lua
- tags: openresty, ngx-lua, cosocket, http-1-1, keepalive, pipelining, mtls, luarocks, nginx
