Common fragment caching for web documents

A computer-implemented method comprising:

• receiving, by a server application and from a client device, a query for a first web page of a plurality of web pages, wherein a persistent storage is configured to store programmatic content that defines the plurality of web pages, and wherein the programmatic content comprises:
• (i) a shared programmatic content that is common to the plurality of web pages, and (ii) for each respective web page of the plurality of web pages, a corresponding page-specific programmatic content that defines the respective web page;
• generating, by the server application and in response to reception of the query, a response comprising the shared programmatic content, a first page-specific programmatic content that defines the first web page, and a predefined token located between the shared programmatic content and the first page-specific programmatic content to separate the shared programmatic content in the response from the first page-specific programmatic content in the response;
• and
• transmitting, by the server application and to the client device, the response, wherein reception of the response is configured to cause the client device to:
• (i) identify the predefined token within the response,
• (ii) write, to a cache memory of the client device, the shared programmatic content based on identifying the predefined token within the response,
• (iii) render, for display on a user interface, the first web page based on the shared programmatic content and the first page-specific programmatic content, and
• (iv) in response to reception of a subsequent event that references a second web page of the plurality of web pages, read the shared programmatic content from the cache memory and begin rendering the shared programmatic content for display on the user interface before receiving from the server application a second page-specific programmatic content that defines the second web page.

A system comprising:

• a cache memory;
• a processor;
• and
• a client application configured to perform, when executed by the processor, operations comprising:
• transmitting, to a server device, a query for a first web page of a plurality of web pages, wherein the plurality of web pages are defined using programmatic content comprising:
• (i) a shared programmatic content that is common to the plurality of web pages, and (ii) for each respective web page of the plurality of web pages, a corresponding page-specific programmatic content that defines the respective web page;
• receiving, from the server device, a response comprising the shared programmatic content, a first page-specific programmatic content that defines the first web page, and a predefined token located between the shared programmatic content and the first page-specific programmatic content to separate the shared programmatic content in the response from the first page-specific programmatic content in the response;
• based on receiving the response, identifying the predefined token within the response;
• based on identifying the predefined token within the response, writing, to the cache memory, the shared programmatic content;
• rendering, for display on a user interface, the first web page based on the shared programmatic content and the first page-specific programmatic content;
• and
• in response to reception of a subsequent event that references a second web page of the plurality of web pages, reading the shared programmatic content from the cache memory and beginning rendering the shared programmatic content for display on the user interface before receiving from the server device a second page-specific programmatic content that defines the second web page.
