Please suggest a better word instead of forcibly for this case.
functionality of forcibly getting data from server..
So the data is not coming from the server automatically; you need to "force" it to come. However, I think that forcibly is not the right word here. What really happens in this case: the Refresh button makes the app take the data from the server/db by passing the cache. So I want to emphasize that by hitting Refresh the user "forces" to get data to come NOT from cache.
