|
This enumerated attribute defines the pragma that can alter servers and user-agents behavior. The value of the pragma is defined using the content and can be one of the following:
|
||
|
|
|
||
|
|
content-language [Trashed]
|
||
|
|
This pragma defines the default language of the page.
|
||
|
|
Usage note:
|
||
|
|
do not use this pragma as it is obsolete. Use the global lang attribute on the <body> element instead.
|
||
|
|
|
||
|
|
content-type [Trashed]
|
||
|
|
This attribute defines the MIME type of the document, eventually followed by its character set. It follows the same syntax as the HTTP content-type entity-header field, but as it is inside an HTML Element, most values are not possible. Therefore the valid syntax for its content is the literal string 'text/html' eventually followed by a character set with the following syntax:'; charset=IANAcharset' where IANAcharset is the preferred MIME name for a character set as defined by the IANA.
|
||
|
|
Usage note:
|
||
|
|
Do not use this pragma as it is obsolete. Use the charset attribute on the <meta> element instead.
|
||
|
|
As the <meta> may not be used to change the type of a document in an XHTML document, or in an HTML5 document following the XHTML syntax, never set MIME type to an XHTML MIME type that way. It would be incorrect.
|
||
|
|
Only an HTML document can use the content-type, so most of it is redundant: that's why it has been obsoleted and replaced by the charset attribute.
|
||
|
|
|
||
|
|
default-style
|
||
|
|
This pragma specifies the preferred stylesheet to be used on the page. The content attribute must contain the id of a <link> element whose href attribute links to a CSS stylesheet, or the id of a <style> element which contains a CSS stylesheet.
|
||
|
|
|
||
|
|
refresh
|
||
|
|
This pragma specifies:
|
||
|
|
the number of seconds until the page should be reloaded, if the content attribute contains only a positive integer number;
|
||
|
|
the number of seconds until the page should be redirected to another, if the content attribute contains a positive integer number followed by the string ';url=' and a valid URL.
|
||
|
|
|
||
|
|
set-cookie [Trashed]
|
||
|
|
This pragma defines a cookie for the page. Its content must follows the syntax defines in the IETF HTTP Cookie Specification.
|
||
|
|
Note:
|
||
|
|
Do not use this pragma as it is obsolete. Use the HTTP header set-cookie instead.
