Hey Jan,
I would guess that the txt-file is being cached. Maybe you can teach you
webserver (Apache, that is) to output additional headers [1] when the
resource
http://www.tappenbeck.net/osm/haiti/data/data_haiti/health_facility_paho_poi.txt
is requested.
Currently the server answers with:
hi !
i insert poi-data via a txt file into a map like
http://www.tappenbeck.net/osm/haiti/index.php?id=1&type=3&zoom=12&lat=18.57882&lon=-72.27869
and after update the data on the server the new data will now show
automatic by the next side-connection. even F5 did not help every time -
