Dynamic page metadata

HTML defines some elements that refer to information that is managed as page metadata on portal pages. You can use the dynamic page metadata rewriting feature to place this information into the static HTML code automatically.

The dynamic page metadata rewriting feature affects the HTML tags <base>, <title>, and <meta>. Enable the rewriting for each of these tags by modifying the following page metadata:

  • Set spa.ex.base.enabled to true. The default is false.
  • Set spa.ex.title.enabled to true. The default is false.
  • Set spa.ex.meta.enabled to true. The default is false.

If you enable the previous settings, the following rewrites occur:

  • spa.ex.base.enabled

    The href attribute of the <base> tag is replaced by the base URL to the current page.

  • spa.ex.title.enabled

    The text value of the <title> tag is replaced by the page title that is using the currently requested location.

  • spa.ex.meta.enabled

    If the <meta> tag contains an http-equiv attribute, the content attribute specifies the requested HTTP response header.

    If the <meta> tag contains a name attribute, the rewriting depends on the value of the attribute. Depending upon the value of the name attribute, the content attribute is replaced by one of the following options:

    • description

      The description of the portal page in the currently requested location.

    • csrf_param

      The name of the FORM parameter for CSRF protection.

    • csrf_token

      The CSRF token for the current request.

    • generator

      The name or version of the HCL portal server that is hosting the page.
