When should I empty which cache?
General Information
There are three types of caches you should know about:
Typo3 Page Cache stores the ee.ethz pages to grant visitors a faster access.
Real URL cache stores the links to each ee.ethz page.
Browser Page Cache stores all pages you visit in your browser to grant you a faster access to the pages you already visited. This has nothing to do with the ee.ethz Typo3 environment.
How to empty each of them you see in Question 2 "How to empty the cache?"
Answer
It may happen that the information stored in the cache is not up-to-date due to changes you did recently. This sometimes causes some problems. Typical problems and approaches are listed below.
If you click on a link (e.g. in the menu) in the frontend and a wrong page appears, even tough you linked everything right, there may be a cache-problem. -> Empty the Real URL Cache and try again.
You edited a page and your browser still shows the old page. -> Empty the Browser Page Cache and if that doesn't help, empty the Typo3 Page Cache
