Properties

Methods

checketag()

Check an etag to see if we need to send the page again or not.

public checketag(Context $context, string $tag) : bool
Parameters
$context : Context

The context object for the site

$tag : string

The etag value to check

Return values
bool

checkmodtime()

Check a timestamp to see if we need to send the page again or not.

public checkmodtime(Context $context, string $time) : bool

This always returns FALSE, indicating that we need to send the page again. The assumption is that pages that implement etags will override this function appropriately to do actual value checking.

Parameters
$context : Context

The context object for the site

$time : string

The time value to check
