Introduction

**Hint!** The JumpURL functionality is deprecated and might be removed in future versions.


.. _what-does-it-do:

What does it do?
^^^^^^^^^^^^^^^^

This Extension bundles the JumpURL functionality of TYPO3. JumpURL consists of
two components: link tracking and secure file access.


.. _introduction-link-tracking:

Link tracking
^^^^^^^^^^^^^

The redirection to external URLs will be handled by a request to TYPO3. This allows the tracking
of clicks on links to external pages. Such a URL might look like this:

http://mytypo3.tld/index.php?id=1&jumpurl=http%3A%2F%2Fwww.typo3.org&juHash=XXX

When this URL is processed by TYPO3 the user will be redirected to http://www.typo3.org if
the sumitted juHash is valid.

The same functionality can be used for file and email links.


.. _introduction-secure-file-access:

Secure file access
^^^^^^^^^^^^^^^^^^

JumpURL can also make files downloadable that are not directly accessible by the web server.
This feature is called "JumpURL secure".

A secure JumpURL link will deliver a file if the submitted hash matches. The record that
references the file needs to be accessible by the current user. When the referencing
record is removed or hidden the file will not be delivered to the user any more.
