Мне необходимо написать так, что если метод не POST (GET, HEAD), то выдавать не 0.

map $request_method $cache_hit {
  "~*post" 0;
  default 1;
}

map $request_method $cache_hit {
  POST    0;
  default 1;
}

set $cache_hit 1;

  # POST requests and urls with a query string should always go to PHP.
  if ($request_method = POST) {
    set $cache_hit 0;
  }

  if ($query_string != "") {
    set $cache_hit 0;
  }
   
  # Don't cache uris containing the following segments.
  if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
    set $cache_hit 0;
  }
   
  # Don't use the cache for logged-in users or recent commenters.
  if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {
    set $cache_hit 0;
  }

map $query_string $check_query_string {
  ""       0;
  default  1;
}

map $request_uri $check_request_uri {
  "~*(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)"  1;
  default  0;
}

map $http_cookie  $check_cookie {
  "~*comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in"  1;
  default  0;
}


map "$request_method:$check_query_string:$check_request_uri:$check_cookie"  $cache_hit {
  "~^POST"    0;
  "~1"        0;
  default     1;
}

global $product;
$product->list_attributes();

public function list_attributes() {
		wc_get_template( 'single-product/product-attributes.php', array(
			'product'    => $this
		) );
	}

$attributes = $product->get_attributes();
.........
<?php foreach ( $attributes as $attribute ) :
		if ( empty( $attribute['is_visible'] ) || ( $attribute['is_taxonomy'] && ! taxonomy_exists( $attribute['name'] ) ) ) {
			continue;
		} else {
			$has_row = true;
		}
		?>
		<tr class="<?php if ( ( $alt = $alt * -1 ) == 1 ) echo 'alt'; ?>">
			<th><?php echo wc_attribute_label( $attribute['name'] ); ?></th>
			<td><?php
				if ( $attribute['is_taxonomy'] ) {

					$values = wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) );
					echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );

				} else {

					// Convert pipes to commas and display values
					$values = array_map( 'trim', explode( WC_DELIMITER, $attribute['value'] ) );
					echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );
