These variables can be used with the rewrite function.

$serviceUrl

• $serviceUrl[SERVICE_NAME]  - looks up the <service><url> for the <service><role>SERVICE_NAME

$frontend

• $frontend[path] - Gets the Knox path i.e. /gateway/sandbox/

$import

• $import - This function enhances the $frontend function by adding '@import' prefix to the $frontend path. e.g.

  Code Block
  <rewrite template="{$import[&quot;, url]}/stylesheets/pretty.css&quot;;"/>

  . It takes following parameters as options:

  • $import - Adds @import as a prefix to the frontend url. e.g. @import https://localhost:8443/gateway/sandbox
  • $import[&quot;, url] - Adds &quot; as prefix along with @import, the rewritten frontend url will be '@import https://localhost:8443/gateway/sandbox

$prefix

• $prefix - This function enhances the $frontend function just like $import but gives the ability to choose a prefix (unlike a constant @import in case of $import) e.g.

  Code Block
  <rewrite template="{$prefix[&#39;,url]}/zeppelin/components/{**}?{**}"/>

  • $prefix[PREFIX, url] - Adds a supplied PREFIX to the frontend url, e.g. in above case the rewritten url would be 'https://localhost:8443/
