i see lot of questions on how fix overly-aggressive caching ie , ajax can't seem find information on why such thing. there ever reason cache ajax calls?
caching ajax results wise same reasons cache non-ajax responses. don't want make round-trip server if have data in cache. if want force trip made, instruct data not cached via response headers, or use of various other methods cache-busting appending current timestamp request's query-string.
