To create a static resource:
- From Setup, enter Static Resources in the Quick Find
box, then select Static Resources.
- Click New.
- In the Name text box, enter the text that
should be used to identify the resource in Visualforce markup. This name can contain only underscores and alphanumeric
characters, and must be unique in your organization. It must begin with a letter, not
include spaces, not end with an underscore, and not contain two consecutive
underscores.
- In the Description text area, specify an
optional description of the resource.
- Next to the File text box, click Browse to navigate to a local copy of the resource that
you want to upload.
A single static resource
can be up to 5
MB in size, and an organization can have up to 250 MB of static resources, total.
- Set the Cache Control:
-
Private specifies that the static resource data cached
on the Salesforce server
shouldn’t be shared with other users. The static resource is
only stored in cache for the current user’s session.
- Public specifies that the static resource data cached
on the Salesforce server
be shared with other users in your organization for faster load times.
The W3C specifications on
Header Field Definitions has more technical information about
cache-control.
- Click Save.
