[TYPO3] webmarketing-enabled link

[Igor]

Hi, newbie here,
I am looking for an extension or some typoscript trick, to
modify normal link behviour so that a backend-user, when linking
documents for download, could choose whether to ask the downloader (a
public unregistered site-surfer) for a small set of data before giving
the document.


The main goal is to collected some user data ( e-mail, name and company)
before any unregistered user could download something from a site.
Better would be to be able to store those data somewhere :)


The idea would be to modify href links in case of docs so that:

<a href="path-and-name-of-the-doc">download this doc</a>

could get converted into

<a href="script-to-collect-userdata.php?doc=name-of-the-doc">download
this doc</a>


I am quite sure something similar should be already available but i
couldnt figure it out from extension browsing or googling.


Thanks in advance for your precious time.
Igor
