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

该网站的服务器是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

您可以尝试这样的事：

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

SETLOCAL

SET _adsutil=D:\Apps\Scripts\adsutil.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.
)

这对于一个Web根每个CSS文件缓存值设置为5天，然后运行它是这样的：

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

Caching.CMD 1 \site\wwwroot\*.css
Caching.CMD 1 \site\wwwroot\*.js
Caching.CMD 1 \site\wwwroot\*.html
Caching.CMD 1 \site\wwwroot\*.htm
Caching.CMD 1 \site\wwwroot\*.gif
Caching.CMD 1 \site\wwwroot\*.jpg

的痛苦，但可行的种类。

Kind of painful, but workable.

顺便说一句 - 获得价值HttpExpires，坐落在GUI中的值，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

要得到你需要的实际值
