HTTP headers provide vital information required for a HTTP transaction send via http protocol. The general HTTP header format contains colon-separated name - value pairs in the header field. Each of the name-value pair end with a carriage return (CR) and a line feed (LF) character sequence.

General headers and entity headers are the same for both the server and client. All headers in HTTP messages contain the header name followed by a colon (:), then a space, and the value of the header. Header names are case-insensitive (thus, Content-Type is the same as Content-type). The value of a header can extend over multiple lines by The Host request header specifies the host and port number of the server to which the request is being sent. If no port is included, the default port for the service requested (e.g., 443 for an HTTPS URL, and 80 for an HTTP URL) is implied. A Host header field must be sent in all HTTP/1.1 request A de facto standard for identifying the original host requested by the client in the Host HTTP request header, since the host name and/or port of the reverse proxy (load balancer) may differ from the origin server handling the request. I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers. The "Host" header field in a request provides the host and port information from the target URI, enabling the origin server to distinguish among resources while servicing requests for multiple host names on a single IP
