Persistency of resource requests and responses in proxied communications
The disclosure is generally directed towards a client device agent (e.g., a network agent) learning that a service domain is authenticated via a corresponding suffix proxy domain.

Inline load balancing
Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN. To direct the data message to the identified DCN, the load balancer in some embodiments changes the destination address (e.g., the destination IP address, destination port, destination MAC address, etc.) in the data message from the address of the identified DCN group to the address (e.g., the destination IP address) of the identified DCN. |

Network safety rules in a distributed computing environment
A central networking system supports efficient identification and analysis of problems that occur at associated nodes on the network. Using network monitoring rules, the central networking system samples data from a subset of nodes in response to an indication that an error or problem has occurred on the network. If the collected sample data is determined to satisfy certain network conditions, the central networking system proceeds to perform network operations on nodes of the entire network, as appropriate. Thus, the system does not need to collect data from every node in a large network to address potential network threats. The central networking system also defines rules for detecting when a node experiencing a problem violates safety conditions such that it is impossible or inadvisable to pull analytical data from the node.

Method of producing a self-supported electrode film in a wet process without organic solvent
For production of electrodes in batteries, capacitors, their hybrids, as well as fuel cells or electrolyzers, a self-supported electrode film is produced by providing an aqueous dispersion of a powder mix of active material and binder polymer, drying and kneading the powder mix into a malleable substance and forming it into an electrode film by calendering. The process is useful for low-cost, large-scale production and is environ-mentally friendly, as no organic solvent is used. |
