HTML META cache

먼가 테스트 하다보니..
Firefox에서 이런 메타 태그가 보여서 성능 향상에 영향을 미칠까 하고 검색을 해보았지만..

CACHE-CONTROL <META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE"> HTTP 1.1. Allowed values = PUBLIC | PRIVATE | NO-CACHE | NO-STORE.    Public - may be cached in public shared caches  Private - may only be cached in private cache  no-Cache - may not be cached  no-Store - may be cached but not archived The directive CACHE-CONTROL:NO-CACHE indicates cached information should not be used and instead requests should be forwarded to the origin server. This directive has the same semantics as the PRAGMA:NO-CACHE.  Clients SHOULD include both PRAGMA:NO-CACHE and CACHE-CONTROL:NO-CACHE when a no-cache request is sent to a server not known to be HTTP/1.1 compliant.  Also see EXPIRES.  Note: It may be better to specify cache commands in HTTP than in META statements, where they can influence more than the browser, but proxies and other intermediaries that may cache information.

정적 데이터에는 유효하나(캐싱된거 다시 쓰니)
동적 데이터(php 라던가?)는 이래저래 의미가 없을 듯 하다.
