网页页头meta详解 Content-Type, Content-Language等,意思、作用和用法

  HTTP-EQUIV类似于HTTP的头部协议,它回应给浏览器一些有用的信息,以帮助正确和精确地显示网页内容。常用的HTTP-EQUIV类型有:

  1、Content-Type和Content-Language (显示字符集的设定)

  说明:设定页面使用的字符集,用以说明主页制作所使用的文字已经语言,浏览器会根据此来调用相应的字符集显示page内容。

  用法:
      

  注意: 该META标签定义了HTML页面所使用的字符集为GB2132,就是国标汉字码。如果将其中的“charset=GB2312”替换成“BIG5”,则该页面所用的字符集就是繁体中文Big5码。当你浏览一些国外的站点时,IE浏览器会提示你要正确显示该页面需要下载xx语支持。这个功能就是通过读取HTML页面META标签的Content-Type属性而得知需要使用哪种字符集显示该页面的。如果系统里没有装相应的字符集,则IE就提示下载。其他的语言也对应不同的charset,比如日文的字符集是“iso-2022-jp ”,韩文的是“ks_c_5601”。
      
  Content-Type的Content还可以是:text/xml等文档类型;
  Charset选项:ISO-8859-1(英文)、BIG5、UTF-8、SHIFT-Jis、Euc、Koi8-2、us-ascii, x-mac-roman, iso-8859-2, x-mac-ce, iso-2022-jp, x-sjis, x-euc-jp,euc-kr, iso-2022-kr, gb2312, gb_2312-80, x-euc-tw, x-cns11643-1,x-cns11643-2等字符集;Content-Language的Content还可以是:EN、FR等语言代码。

  2、Refresh (刷新)

   说明:让网页多长时间(秒)刷新自己,或在多长时间后让网页自动链接到其它网页。
   用法:
      http://www.xia8.net“>
   注意:其中的5是指停留5秒钟后自动刷新到URL网址。

  3、Expires (期限)

   说明:指定网页在缓存中的过期时间,一旦网页过期,必须到服务器上重新调阅。
   用法:
      
   注意:必须使用GMT的时间格式,或直接设为0(数字表示多少时间后过期)。

  4、Pragma (cach模式)

   说明:禁止浏览器从本地机的缓存中调阅页面内容。
   用法:
   注意:网页不保存在缓存中,每次访问都刷新页面。这样设定,访问者将无法脱机浏览。

  5、Set-Cookie (cookie设定)

  说明:浏览器访问某个页面时会将它存在缓存中,下次再次访问时就可从缓存中读取,以提高速度。当你希望访问者每次都刷新你广告的图标,或每次都刷新你的计数器,就要禁用缓存了。通常HTML文件没有必要禁用缓存,对于ASP等页面,就可以使用禁用缓存,因为每次看到的页面都是在服务器动态生成的,缓存就失去意义。如果网页过期,那么存盘的cookie将被删除。
   用法:
