Hello, I have several questions to ask about refresh_pattern
sometimes I see configuration as refresh_pattern -i *.ico$ refresh_pattern -i .(css|js|xml) #multiple extensions refresh_pattern \.(css|js|xml) refresh_pattern \.(css|js|xml)$ refresh_pattern -i .(css|js|xml)$ refresh_pattern .(\?.*)?$ Please can anyone explain what is the difference between each example and I have also another question like how to cache multiple extensions using the same rule incase it was dynamic or static example : #I know this rule catches dynamic website or file but i dont know how to deal with multiple extensions like gif , jpeg , png refresh_pattern .(\?.*)?$ Why we put $ , ? or \?.* Thank you
