Improve Performance with HTML Page Caching for Communities in Site.com

HTML caching lets you improve the performance and page rendering of your community’s Site.com site by controlling how often the generated markup of the page is reloaded.

Required Editions

User Permissions Needed
To build, edit, and manage a community’s Site.com custom pages:

OR

Site.com Publisher User field enabled on the user detail page

AND

Site administrator or designer role assigned at the site level

Lets say 100 people visit the page at the same time. Without caching, the page makes 100 separate requests for the same markup, slowing performance considerably. However, with caching enabled, the page markup is requested and retrieved only one time—the first time someone visits the page. Any subsequent page requests during a set time period are returned from the cache. When the specified time period expires, the cache is refreshed.

Note
Note The caching duration applies only to community pages that are accessed by guest users. When a user logs in to access the page, caching is disabled.
  1. In Site.com Studio, open the page.
  2. In the Cache Duration (Minutes) field of the Cache section of the Properties tab, specify the length of time to cache the page.
    By default, the caching duration of a page is set to 30 minutes.

    To disable caching, set the page’s caching duration to 0.
