Class Headers

java.lang.Object
com.renomad.minum.web.Headers
public final class Headers extends Object
Details extracted from the headers. For example, is this a keep-alive connection? what is the content-length, and so on. Here is some detail from Wikipedia on the subject:

HTTP header fields are a list of strings sent and received by both the client program and server on every HTTP request and response. These headers are usually invisible to the end-user and are only processed or logged by the server and client applications. They define how information sent/received through the connection are encoded (as in Content-Encoding), the session verification and identification of the client (as in browser cookies, IP address, user-agent) or their anonymity thereof (VPN or proxy masking, user-agent spoofing), how the server should handle data (as in Do-Not-Track), the age (the time it has resided in a shared cache) of the document being downloaded, amongst others.
