[ka-Map-users] Refresh layers with tilesource=cache

[Antonio Garcia]

Hello, I have got a problem with the tile.php of a WMS layer.
 
This layer is of the spanish catastro.
 
There are some tiles that I can't see, and I go to see the files in the tmp and see tiles white.
 
When I go to kamap in another time the tiles are white again, and I have got that delete the tiles in the directory tmp.
Then KAMAP redraw it ok
 
I think that kamp would must  can refresh the screen with this problem even when the configuration of this layer is tilesource: cache
 
 
In the tile.php there is this code:
 
//acquire shared lock for reading to prevent a problem that could occur
//if a tile exists but is only partially generated.
flock($fpLockFile, LOCK_SH);
$h = fopen($szCacheFile, "r");
header("Content-Type: ".$szImageHeader);
header("Content-Length: " . filesize($szCacheFile));
header("Expires: " . date( "D, d M Y H:i:s GMT", time() + 31536000 ));
header("Cache-Control: max-age=31536000, must-revalidate" );
fpassthru($h);
fclose($h);
//release lock
fclose($fpLockFile);
/* bug 1253 - root permissions required to delete cached files */
umask($orig_umask);
 
 
Can somebody help me? Please
