    사용하려면 저장관리모듈(storage management module)이 필요하다.

    <p>RFC 2616에 따르면 홉간(hop-by-hop) HTTP 헤더는 캐쉬에
    저장하지 않는다. 홉간 HTTP 헤더에는 다음과 같은 것이 있으며,
    <code class="directive">CacheIgnoreHeaders</code> 설정과 관계없이
    <em>어떤</em> 경우에도 캐쉬에 저장되지 않는다.</p>

    <ul>

    안되는 HTTP 헤더를 추가로 지정한다. 예를 들어, 쿠키(cookie)를
    캐쉬에 저장하면 안되는 경우가 있다.</p>

    <p><code class="directive">CacheIgnoreHeaders</code>는 캐쉬에 저장하지
    않을 HTTP 헤더들을 공백으로 구분한 목록을 받는다. (RFC 2616에
    따라) 캐쉬에 홉간 헤더만 저장하지 않으려면,
    <code class="directive">CacheIgnoreHeaders</code>를

    <p>문서에 만기시간은 없지만 최근수정일이 있는 경우 최근수정일
    이후 지난 시간으로 만기시간을 계산한다.
    <code class="directive">CacheLastModifiedFactor</code> 지시어는
    만기시간을 계산하는 다음 공식에서 사용할 <var>factor</var>를
    지정한다:

    <code>expiry-period = time-since-last-modified-date * <var>factor</var>
    expiry-date = current-date + expiry-period</code>

    예를 들어, 문서가 10 시간 전에 마지막으로 수정되었고 <var>factor</var>가
    0.1이라면 만기기간은 10*01 = 1 시간이 된다. 현재 시간이
    3:00pm이라면 만기시간은 3:00pm + 1시간 = 4:00pm이다.

    만기기간이 <code class="directive">CacheMaxExpire</code> 보다 길다면
    <code class="directive">CacheMaxExpire</code>를 사용한다.</p>

    <div class="example"><p><code>
      CacheLastModifiedFactor 0.5
    </code></p></div>
