<div>I think I'm missing something obvious:</div><div><br></div>I've setup tilecache.cgi to construct a cache of the NAIP imagery on my local server. So far, this works great as an "Custom" imagery source in Potlatch:<div>
<br></div><div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; "><a href="http://navigator.er.usgs.gov/naip/tilecache.cgi/1.0.0/0/!/!/" target="_blank" style="color: rgb(42, 93, 176); ">http://navigator.er.usgs.gov/naip/tilecache.cgi/1.0.0/0/!/!/</a>!</span></div>
<div><br></div><div>But I would also like to be able to hit the disk cache directly, ala:</div><div><br></div><div><a href="http://navigator.er.usgs.gov/naip/0/!/!/">http://navigator.er.usgs.gov/naip/0/!/!/</a>!</div><div>
<br></div><div>I can successfully load individual images from the cache like this:</div><div><br></div><div><a href="http://navigator.er.usgs.gov/naip/0/16/15060/25346.png">http://navigator.er.usgs.gov/naip/0/16/15060/25346.png</a></div>
<div><br></div><div>When I look at the Apache error log, I see "Cache hit:... Tile: x: 15060, y: 40188, z: 16</div><div><br></div><div>But in the naip/0/16/15060 directory, there are only four PNGs with filenames nothing like "40188.png":</div>
<div><br></div><div>25345.png, 25346.png, 25347.png, 25348.png, </div><div><br></div><div>My tilecache.cfg looks like this:</div><div><br></div><div><span class="Apple-style-span" style="font-family: monospace; font-size: medium; white-space: pre-wrap; ">[cache]</span></div>
