HttpProxy

An outbound HTTP proxy every llm4s HTTP client routes through: the llm4s.http.proxy block.

llm4s.http.proxy {
 url           = "http://proxy.corp:3128"
 username      = ${?LLM4S_PROXY_USER}
 password      = ${?LLM4S_PROXY_PASSWORD}
 nonProxyHosts = ["localhost", "*.internal"]
}

The proxy is an HTTP proxy: plain-http requests go to it in absolute form, https ones through a CONNECT tunnel. Proxy authentication is HTTP Basic; PAC files and Kerberos/NTLM are not supported.

nonProxyHosts lists the hosts reached directly. An entry is a host name or address matched exactly (localhost), a domain suffix (*.internal or .internal, which match internal itself too), a prefix (10.*), or * for every host; matching ignores case. A CIDR range is not supported. The default is the loopback addresses (HttpProxy.DefaultNonProxyHosts); setting the list replaces it.

The password is redacted in toString. Build one with HttpProxy.apply or HttpProxy.fromUrl and adjust it with the with* setters; the constructor is private, so a new field never breaks a caller.
