[ka-Map-users] Caching timeout explanation

[Munro, Derek]

Hi Paul:
 
Two questions:
 
1. Could you explain the time out feature in caching? This appears to be
in tile.php:
 
header("Expires: " . date( "D, d M Y H:i:s GMT", time() + 31536000 ));
header("Cache-Control: max-age=31536000, must-revalidate" );
 
I assume that this is the number of seconds before a given tile will
time out from the data stamp?
 
What I want is to capture a series of tiles once that will not expire.
How do I do that (simply rem out these two lines)?
 
2. Is there any work being done on a *query current mouse position* so
that the current latitude and longitude would appear on the browser
page, for example, after a double mouse click?
 
Thanks,
 
Derek Munro
