httpcat is a simple utility for constructing raw HTTP requests on the command line.

HTTPie CLI: human-friendly HTTP client for the API era

HTTPie (pronounced aitch-tee-tee-pie) is a command-line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible. HTTPie is designed for testing, debugging, and generally interacting with APIs & HTTP servers. The http & https commands allow for creating and sending arbitrary HTTP requests. They use simple and natural syntax and provide formatted and colorized output.

httpcat's Issues

why Content-Length value differ from 5 to 6 on README?

httpcat/README.md

Lines 58 to 88 in cc2a30e

	## Usage
	Interactively create a request and send it with `nc`:
	```bash
	$ httpcat -v | nc httpbin.org 80
	POST /post HTTP/1.1
	> POST /post HTTP/1.1\r\n
	Host: httpbin.org
	> Host: httpbin.org\r\n
	Content-Length: 6
	> Content-Length: 6\r\n
	> \r\n
	Hello
	> Hello
	```
	Specify the whole request in the arguments. Here `''` represents an empty
	line which will be converted to `\r\n\` separating the headers and the
	body. Note also that the omitted `HTTP-Version` is auto-completed:
	```bash
	$ httpcat -v 'POST /post' 'Host: httpbin.org' 'Content-Length: 5' '' 'Hello' | nc httpbin.org 80
	> POST /post HTTP/1.1\r\n
	> Host: httpbin.org\r\n
	> Content-Length: 5\r\n
	> \r\n
	> Hello
	```

Feature request: Dynamic `Content-Type` header option

How about an option to do the automatic Content-Type header calculation based on the body size? It could be an argument to httpcat to enable this header override.
I often find myself editing the body content quickly and request fails due to wrong Content-Type value.
