[mapserver-users] Mapserver and TileCache, parsing error thereby no cached images

[Rahkonen Jukka]

Hi,

Perhaps it has something to do with newline characters?
[line 82]: '  type=WMS\n'

 Hi all,

Original question was posted here: http://gis.stackexchange.com/questions/19459/tilecache-and-mapserver-not-producing-images-and-raising-parsing-error

Just a forewarning, I will try to be as extensive with my question as possible. Due to a number of reasons why this might not be working, I have posted all sorts of portions of my debugging below.

Web map located here<http://rinnerweb.arts.ryerson.ca/moot2_dev>

Tile cache is being setup as a test run for the "hii_5" layer in OpenLayers. MapServer is the backend.

I am trying to get TileCache to cache images of my MapServer WMS. However, no images are produced. The TileCache is "trying" to load the tiles (as you can see on the live page), however, no images are returned.

When I follow the path<http://rinnerweb.arts.ryerson.ca/cgi-bin/tilecache.cgi?LAYERS=HII_railroads&FORMAT=image/png&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG:3857&BBOX=-10592586.767623,5113378.756775,-9340242.496373,6365723.028025&WIDTH=256&HEIGHT=256> of one of the image tiles, I see this error:

  *   and the template<http://rinnerweb.arts.ryerson.ca/cgi-bin/mapserv.exe?map=/ms4w/Apache/htdocs/moot2_dev/hii_railroads.map&> return blank

Here are the relevant mapfile, tilecache.cfg, and openlayers source:

Not sure how much help I will get here, but the questions out there for anyone to take a stab at it!
