[Tilecache] TileCache generates weird URLs

[Arnaud Diederen]

Hello all,

I've installed tilecache with mod_python recently, but I cannot get very
far, regarding the use of the "capabilities" the service advertises.

According to the TMS specification (
http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification), a request
on
http://labs.metacarta.com/wms-c/Basic.py/1.0.0 should advertise tile maps at
the URLs of the form:

  http://labs.metacarta.com/wms-c/Basic.py/1.0.0/linktothepast
  http://labs.metacarta.com/wms-c/Basic.py/1.0.0/basic

but it does advertise URLs of the form:

  http://labs.metacarta.com/wms-c/Basic.py/1.0.0/1.0.0/linktothepast
  http://labs.metacarta.com/wms-c/Basic.py/1.0.0/1.0.0/basic

instead.
Those urls are clearly wrong, and the server errors on requests at those.
Removing the second, duplicate "1.0.0/" makes it work fine.

Now, if I use the URL:
http://labs.metacarta.com/wms-c/Basic.py/1.0.0/linktothepast
The tile sets advertised have (even) weird(er) URLs:

http://labs.metacarta.com/wms-c/Basic.py/1.0.0/linktothepast/1.0.0/linktothepast/0
http://labs.metacarta.com/wms-c/Basic.py/1.0.0/linktothepast/1.0.0/linktothepast/1
http://labs.metacarta.com/wms-c/Basic.py/1.0.0/linktothepast/1.0.0/linktothepast/2

Again, those are wrong. Removing the duplicate "1.0.0/linktothepast" makes
them work ok.

Am I doing anything wrong, or is it a bug?

It seems OpenLayers builds references to the images itself, and does not
need to perform such requests to the service, so I guess it might have gone
unnoticed...

Best regards,
         A.
