Hi, I'd like to use cache to improve performance of a page where I do a custom SQL query. I use the following code, but the code to retrieve data from cache is never called: if($cache = cache_get('my_content') && !empty($cache->data)) { // Retrieve data from cache $complex_array= unserialize($cache->data); } else {  // Execute query  $complex_array = ...  // Cache result cache_set('my_content', 'cache_page', serialize($complex_array)); } If I have a look at the database content, I don't find any information in the cache_page table...
