Techniques are described for providing one or more clients with direct access to cached data blocks within a persistent memory cache on a storage server. In an embodiment, a storage server maintains a persistent memory cache comprising a plurality of cache lines, each of which represent an allocation unit of block-based storage. The storage server maintains an RDMA table that include a plurality of table entries, each of which maps a respective client to one or more cache lines and a remote access key. An RDMA access request to access a particular cache line is received from a storage server client. The storage server identifies access credentials for the client and determines whether the client has permission to perform the RDMA access on the particular cache line. Upon determining that the client has permissions, the cache line is accessed from the persistent memory cache and sent to the storage server client.

Webpage loading method and system. While browsing a webpage, a user can uninterruptedly browse subsequent contents without waiting for page loading since whether subsequent pages need to be loaded is determined by the prediction of remaining page browsing time. The method comprises: in response to a page loading completion event, recording a current page end scroll bar value, a current page initial scroll bar value and a current page loading completion moment; in response to a scroll bar scrolling event, recording a present scroll bar triggering moment and a present scroll bar value; calculating a page browsing speed and a remaining page browsing time; and when the remaining page browsing time meets a preset condition, sending to a server a page acquisition request related to subsequent pages of the current page and loading and updating page data about the subsequent pages to the end of the current page.

Described are methods, systems and computer readable media for performance logging of complex query operations.

Systems and methods are provided for improving web-based document retrieval and object manipulation. In an implementation, objects within web documents (e.g., a web page) are manipulated when the objects are visible through a viewport of a user's web browser. According to a method, an object selected from a web document is manipulated when that selected object is displayed within the viewport of the user's browser. The manipulation may include downloading content associated with the stored object and additionally, or alternatively, executing a script associated with the stored object. Additionally, or independently, methods may be provided for blocking the download of an object in a retrieved web document until that object is displayed or visible in the user's browser viewport.

Disclosed are an apparatus and a method for outputting web content. The apparatus and method can prevent rendering performance from being degraded in some operating systems when web content (web document) is output through a web browser.

Described are methods, systems and computer readable media for data source refreshing.

Methods and systems for rending medical images within a web browser application. The web browser application retrieves a worklist and automatically determines an image study from the worklist to be cached. The web browser application retrieves at least one medical image included in the image study. The web browser application creates a web database for storing the at least one medical image within the browser application. When a user selects a medical image for display within the web browser, the web browser application determines whether the medical image is stored in the web database. When the medical image is stored in the web database, the web browser application retrieves the medical image from the web database. When the medical image is not stored in the web database, the web browser application retrieves the medical image from a remote image repository.

A method of delivering content includes, at a node in a network, receiving a first file, from a server, for rendering a first webpage. The method also includes transmitting the first file to a client computer system. The method also includes extracting a first hyperlink to a second webpage from the first file. The method also includes prefetching a second file for rendering the second webpage. The method also includes receiving a request to access a third webpage from the client computer system. The method also includes, in accordance with a determination that the second file can be used for rendering the third webpage, transmitting the second file to the client computer system.

Methods and systems are provided for a browser in a client device that receives a user interface script-code snippet from a web page. A chain logic engine determines whether an in-memory map indicates an output value of prior execution of the UI script-code snippet. If the in-memory map does indicate the output value, it is returned from the in-memory map to generate the user interface. If not, the engine determines whether an in-local storage map indicates the prior executed snippet output. If the in-local storage map indicates the prior executed snippet output, it is returned from the in-local storage map to generate the user interface, and it is stored in the in-memory map. If not, the UI script-code snippet is executed to generate the output value, which is used to generate the user interface, and is stored in the in-memory map and in the in-local storage map.

The present invention relates to an asynchronous cache updating system and a method thereof, wherein the problems of repeatedly retrieving data from the main data source as data in cache systems is deleted after a certain period of time and being able to retrieve cached data only in the second and the subsequent requests are eliminated. The present invention particularly relates to a cache updating system and a method thereof that allows for changing cached data over time without using it and without expecting a request from the user and for updating data stored on the cache systems independently of the validity period of the data.
