The server was acting as a gateway or proxy and did not receive a timely response from the upstream server. 505 HTTP Version Not Supported The server does not support the HTTP version used in the request. 506 Variant Also Negotiates (RFC 2295) Transparent content negotiation for the request results in a circular reference.

In case of a connection loss this protocol may try to recover the connection. If a connection is not used for a long period, the session-layer protocol may close it and re-open it. It provides for either full duplex or half-duplex operation and provides synchronization points in the stream of exchanged messages.
If a host tries to send data through a router (R1) and R1 sends the data on another router (R2) and a direct path from the host to R2 is available (that is, the host and R2 are on the same subnetwork), then R1 will send a redirect message to inform the host that the best route for the destination is via R2. The host should then change its route ...
Internal network virtualization configures a single system with software containers, such as Xen hypervisor control programs, or pseudo-interfaces, such as a VNIC, to emulate a physical network with software. This can improve a single system's efficiency by isolating applications to separate containers or pseudo-interfaces.
Resources may exist in multiple namespaces. Examples of such resources are process IDs, host-names, user IDs, file names, some names associated with network access, and Inter-process communication. Namespaces are a required aspect of functioning containers in Linux. The term "namespace" is often used to denote a specific type of namespace (e.g ...
In computer networking, a host model is an option of designing the TCP/IP stack of a networking operating system like Microsoft Windows or Linux.When a unicast packet arrives at a host, IP must determine whether the packet is locally destined (its destination matches an address that is assigned to an interface of the host).
The latter had been a separate software package in earlier history. By 2007 the term Solaris Containers came to mean a Solaris Zone combined with resource management controls. Later, there was a gradual move such that Solaris Containers specifically referred to non-global zones, with or without additional Resource Management.
A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts. Typically a server accepts connections from clients who request a service function. [4] Every network host is a node, but not every network node is a host.
