Server-side caching for web user interfaces

A server device comprising:

• a memory;
• a processing system having at least one processor, the processing system being configured to perform operations comprising:
• storing, for each of a plurality of users, data for a plurality of widgets that are displayable on a user interface provided by a web application;
• receiving, from the user interface of a client device a plurality of data requests each with an included respective retry number;
• initiating an asynchronous refresh of the stored data of at least a subset of the plurality of widgets in response to the respective retry number being a first retry number below a preconfigured threshold, and initiating a synchronous refresh of the stored data of at least the subset of the stored plurality of widgets in response to the respective retry number being a second retry number equal to or higher than the preconfigured threshold;
• and
• transmitting, to the client device, at least a first response to the plurality of data requests in association with the initiated synchronous refresh or the asynchronous refresh.

A method performed by one or more processors of a server device, the method comprising:

• storing in a memory accessible to the server device, for each of a plurality of users, data for a plurality of widgets that are displayable on a user interface provided by a web application;
• receiving via a network interface of the server device, from the user interface of a client device a plurality of data requests each with an included respective retry number;
• initiating an asynchronous refresh of the stored data of at least a subset of the plurality of widgets in response to the respective retry number being a first retry number below a preconfigured threshold, and initiating a synchronous refresh of the stored data of at least a subset of the plurality of widgets in response to the respective retry number being a second retry number equal to or higher than the preconfigured threshold;
• and
• transmitting via the network interface of the server device, to the client device, at least a first response to the plurality of data requests in association with the initiated synchronous refresh or the asynchronous request.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a server device, causes the server device to perform operations comprising:

• storing in a memory accessible to the server device, for each of a plurality of users, data for a plurality of widgets that are displayable on a user interface provided by a web application;
• receiving, from the user interface of a client device a plurality of data requests each with an included respective retry number;
• initiating an asynchronous refresh of the stored data of at least a subset of the plurality of widgets in response to the respective retry number being a first retry number below a preconfigured threshold, and initiating a synchronous refresh of the stored data of at least a subset of the plurality of widgets in response to the respective retry number being a second retry number equal to or higher than the preconfigured threshold;
• and
• transmitting via the network interface of the server device, to the client device, at least a first response to the plurality of data requests in association with the initiated synchronous refresh or the asynchronous request.
