Caches generated output as a static file to be served directly from the webserver.

Code

function boost_expire_cache($urls, $wildcards, $object_type, $object) {
  global $base_root;
  foreach ($urls as $key => $url) {

    // Decode the url since it may have a query string that has been encoded.

    // We need the extension for the filename.

    $boost['matched_header_info'] = boost_match_header_attributes($boost['header_info']);

    // Issue #2135835 Cache may not be enabled for this type (html/xml/ajax)
