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

Hi,
Maybe the error means what is says and the size of image (256x256 pixels) does not suit any of the supported scales with the given BBOX. WMS-C requests be exactly correct to suit the cached tiles.
QGis and uDig support WMS-C so that they read the GetCapabilities from the service and adjust the GetMap requests accordingly automatically.

Aihe: Re: [mapserver-users] Mapserver and TileCache, parsing error thereby no cached images
My data is in WGS84 Major Auxiliary Sphere (as outputted by ArcGIS).. EPSG:3857
* Using this<http://rinnerweb.arts.ryerson.ca/cgi-bin/mapserv.exe?map=/ms4w/Apache/htdocs/moot2_dev/hii_railroads.map&REQUEST=GetMap&WIDTH=500&HEIGHT=500&LAYERS=HII_railroads&VERSION=1.1.1&SRS=EPSG:3857&bbox=-10995797.347,5031174.730,-7855157.347,7815054.730&MAPUNIT=DecimalDegree&FORMAT=image/png&ClientId=&CLIENTMODE=TiledWmsRasterSource> GetMap request, I have verified that my data is in fact queryable
So I changed a few settings in my tilecache.cfg as so based on the GetMap query:

Still no luck<http://rinnerweb.arts.ryerson.ca/moot2_dev/>, darn.
You can see that layer hii_6 doesnt produce any images and I am given this error when I explore the url<http://rinnerweb.arts.ryerson.ca/cgi-bin/tilecache.cgi?LAYERS=HII_railroads&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A3857&BBOX=-10995797.347,6283519.00125,-9743453.07575,7535863.2725&WIDTH=256&HEIGHT=256> to these tiles:

Hi,
Perhaps it has something to do with newline characters?

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:

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!
