Pre-fetching random-value resource locators
Once resolved, a random-value universal resource locator (RV-URL) identifies a resource on a host server and constitutes an instruction to a local device executing a network transaction to fetch the resource. Embodiments of the invention resolve and pre-fetch an RV-URL from a remote host server and then pre-position, on a client-side of a communications link to the remote server, both resolution information indicating how the RV-URL was resolved and the pre-fetched resource. Later, when the client device is executing a network transaction and encounters an RV-URL, the client device determines whether resolution information for the RV-URL is locally stored. If so, the client device uses the resolution information to resolve the RV-URL to the same value that was used during pre-fetch. The client device then sends a request for the resolved RV-URL. The request is intercepted on the client-side of the communications link, where it is determined whether a locally cached pre-fetched resource corresponds to the intercepted request. If so, the locally cached pre-fetched resource is provided to the local device as a complete response to the request, which can then be discarded. |

System and method for automated hybrid network creation
A global architecture (GLP), as disclosed herein, is based on the thin server architectural pattern; it delivers all its services in the form of web services and there are no user interface components executed on the GLP.

Each component is a microservice, making the overall architecture fully decoupled. Each microservice has fail-over nodes and can scale up on demand. This means the GLP has no single point of failure, making the platform both highly scalable and available. The GLP architecture provides the capability to build and deploy a microservice instance for each course-recipient-user combination. Because each student interacts with their own microservice, this makes the GLP scale up to the limit of cloud resources available—i.e. near infinity. |

Automatic redirection in scale-out cluster environments that perform distributed deduplication
Automatic redirection in scale-out cluster environments that perform distributed deduplication is described.

If the remote procedure call is a write request, the system deduplicates the write request's data, uses the physical connection from the client to the correct node to send the write request and the deduplicated data to the correct node, and enables the correct node to store the deduplicated data. |

Method for manufacturing organic EL display panel, and ink drying device
An ink drying process includes exhausting gas from atmosphere surrounding a substrate and drying ink through placing the substrate in a predefined pressure or less to form organic functional layers. Exhausting of gas includes: reducing, during a first period, pressure of the atmosphere from standard atmospheric pressure to a first pressure higher than vapor pressure of solvent having the highest vapor pressure among solvents of the ink; and subsequently reducing, during a second period, the pressure of the atmosphere to a second pressure lower than vapor pressure of solvent having the lowest vapor pressure among the solvents. Where pressure of the atmosphere is 10x Pa (X indicating a real number), a change amount average of X per unit time has a greater absolute value during the second period than during the first period. |
