익스 8에서 https로 하면 다운로드가 안되는데 8이하 버전까지 예외처리를 해줘야된다는~

[처리내용]

처리 1) 아파이 웹서버 SSL 캐싱 설정

SSLSessionCache        "shmcb:/supp1/apachedomains/all_domain/logs/ssl_scache(512000)"

SSLSessionCacheTimeout  300

처리 2) 문제가 되는 브라우저에 대해 Pragma 제거

package net.e4net.eiwaf.web.util;

public static void noCache(HttpServletRequest request, HttpServletResponse response) {

response.setHeader("Cache-Control", "no-store");

response.setHeader("Pragma", "no-cache");

response.setDateHeader("Expires", 0);

if (request.getProtocol().equals("HTTP/1.1")) {

response.setHeader("Cache-Control", "no-cache");

}

}

public static void noCacheDownload(HttpServletRequest request, HttpServletResponse response) {

String reqScheme = request.getScheme();

boolean ieSSLBug = false;

if ("https".equals(reqScheme))  {

String userAgent  = StringUtil.nvl(request.getHeader("User-Agent"), StringUtil.EMPTY);

if (userAgent.indexOf("MSIE 6") > -1

|| userAgent.indexOf("MSIE 7") > -1

|| userAgent.indexOf("MSIE 8") > -1) {

ieSSLBug = true;

}

}

   String noCache = ieSSLBug ? StringUtil.EMPTY : "no-cache, ";

response.setHeader("Cache-Control", noCache + "no-store");

response.setHeader("Pragma", noCache);

response.setDateHeader("Expires", 0);

}
