I'm not very familiar with different existing caching mechanisms of modern websites. If someone says that a website has been updated, but it will take "until the morning" for the changes to show, why might that be the case? Even assuming the client can clear their local cache at any time. Does...

There are 20 amino acids and 4 are essential. You can lookup the nutrition facts of anything on google and get results. What I don't like is that google does not tell me which proteins are found in these foods, it just tells you how many grams of anything the food contains.

Are there any good websites that give examples and offer help in Abstract Algebra? I have an awful professor that doesn't use a book and gives bad notes. Needless to say, I'm struggling.
