[mapserver-dev] Communicating Tile Coordinates Between Mapcache and Mapserver

[seandisanti]

Actually, it looks like I was premature in reporting success. This request
returned an image and I believed it to have worked...
http://mapcache_url/?map=/map/ahps/precip.map&shape_path=2015/06/24/nws_precip_1day_observed_20150624&mode=tile&tilemode=gmap&service=WMS&version=1.1.1&request=GetMap&Styles=default&SRS=EPSG:102100&width=256&height=256&format=image/PNG&TRANSPARENT=TRUE&layers=precip_conus&dpi=120&tile=3+4+5&bbox=-14447739.261967285,-6620587.5655673165,1700243.76178827,6592213.57203825

But if I change any tile coordinates or shape_path data, it still only
returns the same image.

My source now looks like: 

<source name="precip_conus" type="wms">
      <getmap>
         <params>
            <map>/map/ahps/precip.map</map>
            <version>1.3.0</version>
            <SRS>EPSG:3857</SRS>
            <CRS>EPSG:3857</CRS>
			<SRS>EPSG:102100</SRS>
			<CRS>EPSG:102100</CRS>
            <TRANSPARENT>TRUE</TRANSPARENT>
            <FORMAT>image/png</FORMAT>
            <LAYERS>conus-raster</LAYERS>

         </params>
      </getmap>
      <http>
         <url>http://mapserver_url</url>
         <headers>
            <User-Agent>mod_mapcache/r175</User-Agent>
            <Referrer>http://mapcache_url/</Referrer>
         </headers>
         <connection_timeout>10</connection_timeout>
	  </http>
   </source>
 
And the tileset is:
<tileset name="precip_conus">
      <source>precip_conus</source>
	  <LAYER>conus-raster</LAYER>
      <cache>precip_cache</cache>
      <grid>g2</grid>
      <format>PNG</format>
      <dimensions>
         <dimension type="regex" name="shape_path"
default="2015/01/01/nws_precip_1day_observed_20150101">^[0-9]{4}\/[0-9]{2}\/[0-9]{2}\/nws_precip_.*_[a-zA-Z]+_[0-9]{8}$</dimension>
      </dimensions>
   </tileset>
