!!! Overview [{$pagename}] is a [proxy] [Service] (a computer [server] or an [application]) that acts as an intermediary for [requests] from [clients] seeking [resources] from other servers. A [client|user-agent] connects to the [{$pagename}], requesting some [resource], such as a file, connection, [WEB] page ([URL]), or other [resource] available from a different server and the [{$pagename}] evaluates the [request] and determines which server to connect the [client|user-agent]. [{$pagename}] is an [Application Layer] device which is an [Observer] and by definition a [Man-In-The-Middle].[{$pagename}] __may not meet the strict definition of a [Proxy]__ as the [End-User] may not have [Consented|Consent] or provided [Permission] to the [proxy]. !! [{$pagename}] [Classifications] A [{$pagename}] may reside on the user's local computer, or at various points between the user's computer and destination servers on the [Internet]. * A [{$pagename}] that passes__ requests and responses unmodified__ is usually called a [gateway] or sometimes a tunneling [proxy] or [Transparent Proxy]. ([SOCKS]) * A forward [proxy] is an Internet-facing proxy used to retrieve from a wide range of sources (in most cases anywhere on the Internet). * A [Reverse Proxy] is usually an internal-facing [proxy] used as a [front-end] to control and protect [access] to a private [Local Area Network] ([LAN]). A [Reverse Proxy] commonly also performs tasks such as * [Access Proxy] * [TLS Proxy] * [Application routes] !! Uses of [{$pagename}] [2] There are of course many legitimate uses for [{$pagename}] including: * [Load Balancing] * providing single point of entry to a private network !!
