hyperlink in a map

[SUBSCRIBE MAPSERVER-USERS Nuri]

Hi,

I have a database dbf, with several defined symbols. They appear in my map
when I run mapserver.

It is possible to insert a hyperlink from those symbols that appear in the
map to an existing URL? If it is, how can do it? What instruction have I
to insert in .map file?

Thank you.
