Hello everyone,

Within an action I send an image to the client. Since the image is not going to change, I would like to set the "Expires" header to a far future date, so that it gets cached by the browser. I set the replace flag to true, as stated in the documentation.

$response = $this->getResponse();
$response->setHeader("Content-Type", "image/jpeg");
$response->setHeader("Expires", "Thu, 15 Apr 2010 20:00:00 GMT", true);
$response->setBody($image);
$response->sendResponse();

When I take a look at the actual response headers, I see:

"Expires: Thu, 19 Nov 1981 08:52:00 GMT, Thu, 15 Apr 2010 20:00:00 GMT"

Here my questions:
(1) Why is the replace header not working? (I experiment the same problem when I try to set the "Cache" header).
(2) Where does the "Thu, 19 Nov 1981 08:52:00 GMT" came from? I never set that one!

I will greatly appreciate any help. Thanks.

Best regards,
Ivan.

have you tried clearing the headers first then setting them? Just a thought...

Yes, I tried using clearHeaders(), but it doesn't seem to work.
