<file:file>

Writes a link to a file. Supports optional desktop integration mode.

If OpenFile is enabled, the connection is from localhost, and not exporting, creates a file:///… URL to the file so that it may be opened locally by the browser. Will additionally open from the server-side when JavaScript enabled.

If there is no body, will write the filename followed by the file size.

OpenFile must be explicitly enabled by setting the com.semanticcms.openfile.servlet.OpenFile.enabled context parameter to true.

For security, OpenFile may only be called from localhost. However, be careful when behind a proxy, as external proxied requests can appear to come from localhost.

OpenFile may be enabled for development but disabled in production by selectively including the semanticcms-openfile-servlet dependency by profile. By not including the dependency in production builds, the code is not simply disabled, but is not even included in production.

The onclick AJAX file opening is disabled when the documents are exporting, as set by the X-com-semanticcms-core-exporting: true header.
