<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>Two
questions:</FONT></SPAN></DIV>
<DIV><SPAN class=209431015-06062005><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>1. Could you explain
the time out feature in caching? This appears to be in
tile.php:</FONT></SPAN></DIV>

<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>header("Expires: " .
date( "D, d M Y H:i:s GMT", time() + 31536000 ));<BR>header("Cache-Control:

<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>I assume that this
is the number of seconds before a given tile will time out from the data
stamp?</FONT></SPAN></DIV>
<DIV><SPAN class=209431015-06062005><FONT face=Arial

<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>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)?</FONT></SPAN></DIV>

<DIV><SPAN class=209431015-06062005><FONT face=Arial size=2>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?</FONT></SPAN></DIV>
