ASP.Net MVC output caching at client side

Question

if i mention cache location at client side so when another client from different pc visit my same cache page then what will happen? i guess if i maintain cache at client side then for next visitor again db trip will occur and cache the data and store at client side......am i right?

 

i guess client side caching will not give much benefit....am i right?

 

please tell me the story of client side caching using asp.net mvc output cache directive.
