This is one of mine:
<source name="tiger2011" type="wms">
<getmap>
<params>
<FORMAT>image/png</FORMAT>
<MAP_IMAGETYPE>agg_qn</MAP_IMAGETYPE>
<LAYERS>Tiger_2011</LAYERS>
<MAP>/u/data/tiger2011-maps/tiger2011-mc.map</MAP>
</params>
</getmap>
<http>
<url>http://localhost/cgi-bin/mapserv-60</url>
</http>
</source>
Here is an OpenLayers app pulling tiles:
http://imaptools.com:8080/demo/tiger-demo2.html
This is what a tile request looks like:
http://imaptools.com:8080/mapcache/?LAYERS=tiger-base&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A900913&BBOX=-10018754.171394,-2504688.5428484,-7514065.6285457,2.4121254682541e-7&WIDTH=256&HEIGHT=256
Note that this is using the Google Spherical Mercator projection.
