From time to time I see this question: how to fill RealURL cache with page addresses?

The answer is pretty simple. Make a new "hide in menu" page. Insert Sitemap there. Logout from Backend. Enter that new page address in the browser bar.

Notice that logging out is essential. RealURL will not cache anything if you are logged in to Backend.

This procedure will fill cache with page addresses. But it will not create cached entries for stuff like tt_news. So this tip is good if you have mostly pages.
