changed Cache-Control default value behavior
The PHP native cache limiter feature has been disabled as this is now managed
by the HeaderBag class directly instead (see below.)
The HeaderBag class uses the following rules to define a sensible and
convervative default value for the Response 'Cache-Control' header:
* If no cache header is defined ('Cache-Control', 'ETag', 'Last-Modified',
and 'Expires'), 'Cache-Control' is set to 'no-cache';
* If 'Cache-Control' is empty, its value is set to "private, max-age=0,
must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));

changed Cache-Control default value behavior
The PHP native cache limiter feature has been disabled as this is now managed
by the HeaderBag class directly instead (see below.)
The HeaderBag class uses the following rules to define a sensible and
convervative default value for the Response 'Cache-Control' header:
* If no cache header is defined ('Cache-Control', 'ETag', 'Last-Modified',
and 'Expires'), 'Cache-Control' is set to 'no-cache';
* If 'Cache-Control' is empty, its value is set to "private, max-age=0,
must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));

changed Cache-Control default value behavior
The PHP native cache limiter feature has been disabled as this is now managed
by the HeaderBag class directly instead (see below.)
The HeaderBag class uses the following rules to define a sensible and
convervative default value for the Response 'Cache-Control' header:
* If no cache header is defined ('Cache-Control', 'ETag', 'Last-Modified',
and 'Expires'), 'Cache-Control' is set to 'no-cache';
* If 'Cache-Control' is empty, its value is set to "private, max-age=0,
must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));

must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));

changed Cache-Control default value behavior
The PHP native cache limiter feature has been disabled as this is now managed
by the HeaderBag class directly instead (see below.)
The HeaderBag class uses the following rules to define a sensible and
convervative default value for the Response 'Cache-Control' header:
* If no cache header is defined ('Cache-Control', 'ETag', 'Last-Modified',
and 'Expires'), 'Cache-Control' is set to 'no-cache';
* If 'Cache-Control' is empty, its value is set to "private, max-age=0,
must-revalidate";
* But if at least one 'Cache-Control' directive is set, and no 'public' or
'private' directives have been explicitely added, Symfony2 adds the
'private' directive automatically (except when 's-maxage' is set.)
So, remember to explicitly add the 'public' directive to 'Cache-Control' when
you want shared caches to store your application resources:
// The Response is private by default
$response->setEtag($etag);
$response->setLastModified($date);
$response->setMaxAge(10);
// Change the Response to be public
$response->setPublic();
// Set cache settings in one call
$response->setCache(array(
'etag' => $etag,
'last_modified' => $date,
'max_age' => 10,
'public' => true,
));
