As suggested by Armin, I modified PM.Layer.PMap.js file in this way:
substitute lines 135-137 with the following ones (copied from highlights)
getUrlParamsAdditional: function() {
var now = parseInt(new Date().getTime() / 100);
return 'timestamp=' + now;
},
Now PMap layers
this function seems to do the job (partially). I have to do more tests
because it works only after a pan
trigger: function myRefreshMap(){
if (this.map) {
map.layers[4].clearGrid();
map.layers[4].redraw(true);
}
},
clearGrid deletes the cache
you could also just have it easy, and if you want layers without any
caching, use the non-tiled (PMap) type
or add a timestamp KVP at the end of each x/y/z request URL, as it's
done for the highlight layer.

The only way it works for is to set session_cache_limiter('nocache') in
index.php and comment the following line. Obviously the effect can be
appreciated after a reaload, not during a live session (not completly true).
The function map.layers[i].redraw(true) isn't useful, I would try with a
Hi Armin,

success. I modified also theindex.php file .

Hi Armin,
if I understood the modifications you suggested have effect on cache
lifetime. I have to do more tries to understand why it doesn't work for me
(I have cache also with PMap setting).
By the way a layer changement (symbology, contents...) won't be appreciate
during a live-session, i
you don't have caching on non-tiled layers, unless the URL for the layer
image is 100% identical. Not that likely if you consider map extent
coordinates for requests having 6 or more decimals for each corner
coordinate pair...

tiled layers are cached by the browser (which is the main advantage
towards non-tiled ones...). In case of changes to the data or map file
(symbols etc) you need to empty the browser cache. I have to check iof
there is a config setting for defining the cache policy (expiration time
of tiles)
could you give it a try and change in lib/map/pmtile/maptile.php
line 55 to
$offset = 1;
I'm not sure if it's this value or the one from the index.php file for
session_cache_expire that defines effectively the cache expiration.
In the case the offset value works I will add some small
11 matches
