Re: [Webtek-devel] no-cache

[max d. <pro...@gm...>]

no.. no such mechanism is implemented (because i never run into this  
problem, although i alreay thouth about this problem ), but it should  
be very easy to implement it.

if this problem is online in one page you can set the request-header  
in the corresponding action:

sub index {
	...
	response->header('Cache-Control' => 'no-cache');
	response->header('Pragma' => 'no-cache');
}

or do it system-wide:

event->register(
	'name' => 'request-prepare-end',
	'method' => sub {
		response->header('Cache-Control' => 'no-cache');
		response->header('Pragma' => 'no-cache');
	}
);
