## What it is
gentleman is a plugin-driven, middleware-oriented HTTP client toolkit for Go, built on top of net/http. It lets developers compose rich HTTP clients from reusable built-in or third-party plugins such as retry policies and Consul-based service discovery.

## Use cases
- build a composable http client in go with plugins
- add retry policy to go http requests
- intercept and modify http traffic on the fly in go
- serialize  xml multipart request bodies in go
- mock http client requests in go tests
- build a domain-specific api client sdk in go
- do consul service discovery for http clients

## When to choose
- you need an extensible, plugin-based http client layer in go
- you want middleware-style interception across the full http lifecycle
- you are building reusable sdk clients for specific apis
- you want dependency-free http client composition with built-in /xml/multipart support

## When to avoid
- you just need simple one-off http requests - net/http or a lighter wrapper suffices
- you need a very actively developed project with frequent releases
- you prefer a non-middleware, straightforward client api

## Facets
- artifact type: library
- maturity: maintenance
- function: http-client, middleware, serialization, plugin-system
- domain: web-development, apis, developer-tools
- platform: go, cross-platform
- tags: http-client-toolkit, fluent-api, retry, service-discovery, http-mocking
