# class HTTP::Request

- HTTP::Request
- Reference
- Object

##
Overview

An HTTP request.

It serves both to perform requests by an `HTTP::Client` and to represent requests received by an `HTTP::Server`.

A request always holds an `IO` as a body. When creating a request with a `String` or `Bytes` its body will be a `IO::Memory` wrapping these, and the `Content-Length` header will be set appropriately.

Class Method Summary

- .from_io(io, *, max_request_line_size : Int32 = HTTP::MAX_REQUEST_LINE_SIZE, max_headers_size : Int32 = HTTP::MAX_HEADERS_SIZE) : HTTP::Request | HTTP::Status | Nil

  Returns a `HTTP::Request` instance if successfully parsed, `nil` on EOF or `HTTP::Status` otherwise.

def remote_address : String? #

The network address that sent the request to an HTTP server.

`HTTP::Server` will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

This property is not used by `HTTP::Client`.

The network address that sent the request to an HTTP server.

`HTTP::Server` will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

This property is not used by `HTTP::Client`.
