I searched everywhere and I can only find solutions that I do not understand (I am not really skilled in web development).
If I understand correctly, the best method is the versionning of javascript and css calls. But I don't understand how I am supposed to implement this in my website or server.
Would someone have an idea or a link for a beginner like me? (the easiest method is the best for me I suppose)
Right now my users have problems with the website, but all problems vanish when the cache is cleared. It's a big problem.
Thanks anyway guys. Have a nice day.
