When Catalyst is used with Apache
Where Apache has "Expire" enabled but relies on Catalyst to use
"no-cache" pragma on its own responses.
Having been using 5.7 and FastCGI Engine
On Upgrading the 5.9 and using the default PSGI behaviour for FastCGI
In 5.7 c->response->redirect() method use to generate the header
"Cache-control: max-age=0" and "Expires" header to reflect the default
expiry time.
In 5.9 the same method now omits the Cache-control header resulting in
the redirects being cached in the browser for the default expiry time.
Workaround - add
$c->response->headers->header( 'Cache-Control' => 'max-age=0' );
Before any call to
$c->response->redirect()
Probably the default behaviour for 5.9 should be to include this max-age
header as the default in the redirect as otherwise people missing this
is testing could have redirects cached unexpectedly in end user browsers.
