java - what does cache means in POST and GET -

-

i have seen that 1 of main difference between post , post not cached cached.

could explain me mean "cache"?

also, if use post or server sends me response. there difference? in of cases, have request data , response, not it?

thanks

get supposed return same result server , not change things @ server side , hence idempotent.

whereas post means can modify @ server(make entry in db, delete etc) , hence not idempotent.

and regards caching data in has been addressed here in nice manner.
