Reduced latency content prefetching with local behavioral profiles

A non-transitory machine-readable medium having program code stored thereon, the program code comprising instructions to:

• communicate a request from an application for content from a website;
• based on communicating the request, receive an indication of a resource where an extension corresponding to the website is available, wherein the extension comprises a behavioral profile for the website;
• retrieve the extension from the resource;
• prefetch content from uniform resource identifiers of the website according to the behavioral profile;
• cache the prefetched content for subsequent use in the application;
• and
• maintain the behavioral profile in the extension locally and in isolation on an endpoint device running the application according to behavior of at least one of a user of the application and the application, wherein the instructions to maintain the behavioral profile comprise instructions to,
• monitor events at the application originating the request;
• and
• update the behavioral profile according to the monitored events.

An apparatus comprising:

• a processor;
• and
• a machine-readable medium having instructions stored thereon that are executable by the processor to cause the apparatus to,
• maintain behavioral profiles for websites for prefetching and locally caching website content, wherein the instructions to maintain the behavioral profiles for websites comprise instructions executable by the processor to cause the apparatus to, based on detecting a request to a website of the websites,
• determine whether an extension for the website is stored in local memory;
• based on determining that the extension for the website is stored in local memory, retrieve the extension from local memory;
• based on determining that the extension for the website is not stored in local memory, retrieve the extension from an authoritative source;
• load the extension in an isolated computing environment;
• invoke a behavioral profile stored in the loaded extension on additional requests to the website to obtain web pages of the website for prefetching;
• prefetch content from the web pages of the website;
• cache the prefetched content;
• and
• update the behavioral profile in the loaded extension based, at least in part, on the additional requests to the website.
