No, it won't. Your server when seeing a request from one of the spiders responds with Vary: user-agent Cache-Control: max-age=72000 Or whatever age you want for the search content.. If you can throw an ETag or Last-Modified in there as well, and have the server react reasonably on If-None-Match / If-Modified-Since conditional requests then even better but that's a bonus. If the request is NOT from one of these spiders you respond with personalized content and headers looking as: Vary: user-agent Cache-Control: private Regards Henrik
