Verify your project
After saving your project, you are redirected to your project page. You will need to verify that the cache-warmer has access to your site. By uploading the "verification file" to your website, we make sure that you allow us to crawl this domain. Just download the verification file or create one yourself with the url suggested in the grey box.
After you have done this, click verify and then your site is ready to be cachewarmed.
If you have just created an account and see the following error on the bottom of the page, don't worry! The error will go away, once your site is verified and will only return when you are really out of requests.
