i found out that i can open google maps with a linkt to a kml-file like that:
http://maps.google.com/maps?q=http://econym.org.uk/gmap/example1.kml
that is exactly what i need, but i don't like to provide a public URL with the Data. Is it possible to pass the data with a post request or get parameter?
Or has anybody another idea how to create a link to google maps with multible markers?
Thanks in advance
