META Tag Information


META tag use in HTML documents have numerous uses, including identifying who created a page, what specs it follows, the keywords for a page, and the description of a page.

  • Formatter
  • Classification
  • Copyright
  • Rating
  • VW96.ObjectType

  • HTdig notification

    Other NAME attributes are useful for specific in-house applications.
    META tags should always be placed in the head of the HTML document between the HEAD tags, before the BODY tag. This is very important with framed pages, as a lot of developers tend to forget to include them on individual framed pages.

    Expires: This tells the browser the date and time when the document will be considered "expired." If a user is using Netscape Navigator, a request for a document whose time has "expired" will initiate a new network request. An illegal Expires date, (such as "0"), is interpreted by the browser as "expires immediately." Dates must be given in the RFC850 format, with a GMT time zone:

    <META HTTP-EQUIV="expires" CONTENT="Tue, 26 Jul 2005 08:21:57 GMT">

    Pragma: This is another way to control browser caching. To use this tag, the value must be "no-cache." When this is included in a document, this prevents Netscape Navigator from caching a page locally.

    <META HTTP-EQUIV="Pragma" CONTENT="no-cache">

    Refresh: This tag specifies a delay in seconds before the Web browser reloads the document automatically. It can also specify an alternative URL for the browser to load, causing one page to switch to another (often used for a "forwarding address").

    <META HTTP-EQUIV="Refresh" CONTENT="0;URL=">

    Remember to place quotation marks around the CONTENT attribute, or your page will be stuck in the mud.

    Set-Cookie: This is yet another method of setting a cookie in the Web browser. if you use an expiration date, the cookie is considered permanent and will be saved to disk; otherwise, it will be considered valid only for the current session and will be erased upon closing the browser.

    <META HTTP-EQUIV="Set-Cookie" CONTENT="cookievalue=xxx; expires=Tuesday, 26-Jul-05 14:32:21 GMT; path=/">

    Window-target: This one specifies the "named window" of the current page, and can be used to prevent a page from appearing inside another framed page.

    <META HTTP-EQUIV="Window-target" CONTENT="_top">
