     837         namespace governed by a potential HTTP origin server listening for TCP connections on a given port. The HTTP server is identified
     838         via the generic syntax's <a href="#uri" class="smpl">authority</a> component, which includes a host identifier and optional TCP port, and the remainder of the URI is considered to be identifying
     839         data corresponding to a resource for which that server might provide an HTTP interface.

    838 </pre><p id="rfc.section.2.1.1.p.3">If the port is empty or not given, port 80 is assumed. The semantics are that the identified resource is located at the server
    839          listening for TCP connections on that port of that host, and the request-target for the resource is path-absolute (<a href="#request-target" title="request-target">Section&nbsp;5.1.2</a>). The use of IP addresses in URLs <em class="bcp14">SHOULD</em> be avoided whenever possible (see <a href="#RFC1900" id="rfc.xref.RFC1900.1"><cite title="Renumbering Needs Work">[RFC1900]</cite></a>). If the path-absolute is not present in the URL, it <em class="bcp14">MUST</em> be given as "/" when used as a request-target for a resource (<a href="#request-target" title="request-target">Section&nbsp;5.1.2</a>). If a proxy receives a host name which is not a fully qualified domain name, it <em class="bcp14">MAY</em> add its domain to the host name it received. If a proxy receives a fully qualified domain name, the proxy <em class="bcp14">MUST NOT</em> change the host name.
    840       </p>
     842</pre><p id="rfc.section.2.1.1.p.3">The host identifier within an <a href="#uri" class="smpl">authority</a> component is defined in <a href="#RFC3986" id="rfc.xref.RFC3986.16"><cite title="Uniform Resource Identifier (URI): Generic Syntax">[RFC3986]</cite></a>, <a href="http://tools.ietf.org/html/rfc3986#section-3.2.2">Section 3.2.2</a>. If host is provided as an IP literal or IPv4 address, then the HTTP server is any listener on the indicated TCP port at
     843         that IP address. If host is a registered name, then that name is considered an indirect identifier and the recipient might
     844         use a name resolution service, such as DNS, to find the address of a listener for that host. The host <em class="bcp14">MUST NOT</em> be empty; if an "http" URI is received with an empty host, then it <em class="bcp14">MUST</em> be rejected as invalid. If the port subcomponent is empty or not given, then TCP port 80 is assumed (the default reserved
     845         port for WWW services).
     846      </p>
     847      <p id="rfc.section.2.1.1.p.4">Regardless of the form of host identifier, access to that host is not implied by the mere presence of its name or address.
     848         The host may or may not exist and, even when it does exist, may or may not be running an HTTP server or listening to the indicated
     849         port. The "http" URI scheme makes use of the delegated nature of Internet names and addresses to establish a naming authority
     850         (whatever entity has the ability to place an HTTP server at that Internet name or address) and allows that authority to determine
     851         which names are valid and how they might be used.
     852      </p>
     853      <p id="rfc.section.2.1.1.p.5">When an "http" URI is used within a context that calls for access to the indicated resource, a client <em class="bcp14">MAY</em> attempt access by resolving the host to an IP address, establishing a TCP connection to that address on the indicated port,
     854         and sending an HTTP request message to the server containing the URI's identifying data as described in <a href="#request" title="Request">Section&nbsp;5</a>. If the server responds to that request with a non-interim HTTP response message, as described in <a href="#response" title="Response">Section&nbsp;6</a>, then that response is considered an authoritative answer to the client's request.
     855      </p>
     856      <p id="rfc.section.2.1.1.p.6">Although HTTP is independent of the transport protocol, the "http" scheme is specific to TCP-based services because the name
     857         delegation process depends on TCP for establishing authority. An HTTP service based on some other underlying connection protocol
     858         would presumably be identified using a different URI scheme, just as the "https" scheme (below) is used for servers that require
     859         an SSL/TLS transport layer on a connection. Other protocols may also be used to provide access to "http" identified resources
     860         --- it is only the authoritative interface used for mapping the namespace that is specific to TCP.

     871</pre><p id="rfc.section.2.1.2.p.3">The primary difference between the "http" and "https" schemes is that interaction with the latter is required to be secured
     872         for privacy through the use of strong encryption. The URI cannot be sent in a request until the connection is secure. Likewise,
     873         the default for caching is that each response that would be considered "public" under the "http" scheme is instead treated
     874         as "private" and thus not eligible for shared caching.

     883         path component is equivalent to an absolute path of "/", so the normal form is to provide a path of "/" instead. The scheme
     884         and host are case-insensitive and normally provided in lowercase; all other components are compared in a case-sensitive manner.
     885         Characters other than those in the "reserved" set are equivalent to their percent-encoded octets (see <a href="#RFC3986" id="rfc.xref.RFC3986.18"><cite title="Uniform Resource Identifier (URI): Generic Syntax">[RFC3986]</cite></a>, <a href="http://tools.ietf.org/html/rfc3986#section-2.1">Section 2.1</a>): the normal form is to not encode them.
