Automatically clear cache from scripts

Question

I received a request to implement browser clear cache automatically when a user starts a session. This is the first time I encounter such a odd request.

Is clear browser cache for a web application a valid requirement for a web application? Should this be considered to be done manually?

Please help me on this matter. p.s.

I know where to ask the programmatic part of this issue on how can I do it, but I am asking: is it worth it from users perspectives and should this be done?

p.s. 2:

I store some data in the sessionStorage and I want that data cleared, on logoff or closed tab or other browser error that will force the user not to logoff

Answer 1

You should never perform an action that a user doesn't expect you to perform (outside of customer service of course). So the question then comes down to whether or not an average user would expect you to clear the cache.

If you are talking about gloabal cache clearing, then you should never clear it automatically whenever a user starts a session.

If you are only talking about the specific cache for a service then it may be a good idea if that service is somehow linked to privacy or security. But then it comes down to managing expectations, and you need to be sure that you inform and educate your users that this will happen whenever they start a session.
