What is the best way to add "Expires" in http header for static content? eg. images, css, js

Web 服务器是 IIS 6.0；语言是经典的 ASP

The web server is IIS 6.0; the language is classical ASP

推荐答案

你可以试试这样的:

@ECHO OFF 
REM ---------------------------------------------------------------------------
REM Caching - sets the caching on static files in a web site
REM syntax 
REM     Caching.CMD 1 d:sitesMySiteWWWRoot*.CSS
REM 
REM   %1 is the WebSite ID
REM   %2 is the path & Wildcard - for example, d:sitesMySiteWWWRoot*.CSS
REM   _adsutil is the path to ADSUtil.VBS
REM ---------------------------------------------------------------------------

SETLOCAL

SET _adsutil=D:AppsScriptsadsutil.vbs

FOR %%i IN (%2) DO (
  ECHO Setting Caching on %%~ni%%~xi
  CSCRIPT %_adsutil% CREATE W3SVC/%1/root/%%~ni%%~xi "IIsWebFile"
  CSCRIPT %_adsutil% SET    W3SVC/%1/root/%%~ni%%~xi/HttpExpires "D, 0x69780"
  ECHO.
)

这会将 Web 根目录中每个 CSS 文件的缓存值设置为 5 天，然后像这样运行它:

Which sets the caching value for each CSS file in a web root to 5 days, then run it like this:

Caching.CMD 1 sitewwwroot*.css
Caching.CMD 1 sitewwwroot*.js
Caching.CMD 1 sitewwwroot*.html
Caching.CMD 1 sitewwwroot*.htm
Caching.CMD 1 sitewwwroot*.gif
Caching.CMD 1 sitewwwroot*.jpg

有点痛苦，但可行.

顺便说一句 - 要获取 HttpExpires 的值，请在 GUI 中设置值，然后运行 ​​

BTW - to get the value for HttpExpires, set the value in the GUI, then run

AdsUtil.vbs ENUM W3SVC/1/root/File.txt

得到你需要的实际值
