2.2.1.4.12 no-cache

This token specifies that HTTP caches are not allowed to use a cached response. The Pragma general-header field is used to include implementation-specific directives, such as the no-cache token, as specified in HTTP 1.0 [RFC1945] section 10.12.

The syntax of the no-cache token is defined as follows.

 no-cache = "no-cache"

Example:

 Pragma: no-cache
