Encoding: gzip is always set in header

Cache route doesn't check if compression of cached page is disabled or if browser accepts gzip.

In cacheroute.inc

184 if (function_exists('gzencode')) {
185 header('Content-Encoding: gzip');
186 }

I suspect it should be something like the following in include/bootstrap.inc

618 if (variable_get('page_compression', TRUE)) {
619 // Determine if the browser accepts gzipped data.
620 if (@strpos($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip') === FALSE && function_exists('gzencode')) {
621 // Strip the gzip header and run uncompress.
622 $cache->data = gzinflate(substr(substr($cache->data, 10), 0, -8));
623 }
624 elseif (function_exists('gzencode')) {
625 header('Content-Encoding: gzip');
626 }
627 }

I wish I had the time and knowledge to fix it, but I don't.
