Inconsistent response headers when using caching via Cache attribute #58598
Description
Symfony version(s) affected
7.1.5
Description
When HTTP caching is set using #[Cache] attribute, and only if HTTP/1.0 (which is the default protocol nginx uses to request upstream when configured as reverse proxy) is used, symfony adds headers that prevent response from being cached.
How to reproduce
#[Route('/test1', name: 'test1')]
public function test1(): Response
{
return (new Response("Hello\n"))
->setPublic()
->setMaxAge(31536000);
}
#[Route('/test2', name: 'test2')]
#[Cache(maxage: 31536000, public: true)]
public function test2(): Response
{
return new Response("Hello\n");
}$ curl --http1.0 -i 'http://127.0.0.1:8002/test1'
HTTP/1.0 200 OK
Cache-Control: max-age=31536000, public
Content-Type: text/html; charset=UTF-8
