While submitting url to Google for indexing, it's showing "Downloaded HTTP response: Expires: Wed, 17 Aug 2005 00:00:00 GMT"

Question

I have just upgrade my site to Joomla 3.6.2.

While submitting the url to Google for indexing, it's showing:

Downloaded HTTP response: Expires: Wed, 17 Aug 2005 00:00:00 GMT

The expiration is 2005, how to correct it?

I have jotcache enable, but there is no browser cache enabled.

Answer 1

Most likely this is set in your .htaccess file - check your .htaccess file for any entries that may cause this. If everything is OK with your .htaccess file, then try disabling JotCache to see if it's the one causing the problem (I highly doubt it though).

Answer 2

It is in the file: public_html/libraries/src/Application/WebApplication.php

if (!$this->response->cachable)   
        {       // Expires in the past.
    $this->setHeader('Expires', 'Wed, 17 Aug 2005 00:00:00 GMT', true);

            // Always modified. 
    $this->setHeader('Last-Modified', gmdate('D, d M Y H:i:s') . ' GMT', true); 
    $this->setHeader('Cache-Control', 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0', false);
