Reload button

[aborruso at spaziogis.it]

Dear user,
I'm developing a web page with mapserver
(http://mapserver.spaziogis.it/cgi-bin/mapserv.exe?map=d%3A%5Clotus%5Cdomino%5Cdata%5Cdomino%5Cspaziogisit%5Cmapserver%5Ccartsic%5Cmap%5Cinsieme.map&imgext=13.305153+38.077841+13.407837+38.180401&imgxy=150+150&zoomsize=2&layer=Ristoranti_e_Trattorie&zoomdir


-1&img.x=152&img.y=161)
but I have a problem: if I put in this page a reload button (more exactly
an Imagefield with this syntax <input type=IMAGE src
="images/icon_redraw.gif" width="19" height="19" name=redraw border=0>) it
makes good its work, but if it is checked zoom botton (in example) the map
is reloaded and also zoomed. I would like only to reload map to show (or
not show) some layers. How can I do it?
Thank you,
