[Tilecache] local wms doesn't work with tc... port configuration problem?

[Alessio Di Lorenzo]

Hi List,

I'm having troubles displaying my local wms service in OL with tilecache.

My tilecache installation works properly (both in cgi mode and mod_python)
if I cache tiles from any remote wms.
The problem comes only when I try to cache tiles from my local wms
(generated with umn-mapserver and staying on the same tilecache's computer):
it shows pink tiles and when I right-click on one of the pink tiles choosing
"View image" in the firefox contextual menu, I can view the following error
instead the tile:

An error occurred: HTTP Error 404: Not Found
  File "/var/www/tilecache/TileCache/Service.py", line 221, in
modPythonHandler
    host )
  File "/var/www/tilecache/TileCache/Service.py", line 205, in
dispatchRequest
    return self.renderTile(tile, params.has_key('FORCE'))
  File "/var/www/tilecache/TileCache/Service.py", line 138, in renderTile
    data = layer.render(tile)
  File "/var/www/tilecache/TileCache/Layer.py", line 411, in render
    return self.renderTile(tile)
  File "/var/www/tilecache/TileCache/Layers/WMS.py", line 29, in renderTile
    tile.data, response = wms.fetch()
  File "/var/www/tilecache/TileCache/Client.py", line 54, in fetch
    response = self.client.open(urlrequest)
  File "urllib2.py", line 387, in open
    response = meth(req, response)
  File "urllib2.py", line 498, in http_response
    'http', request, response, code, msg, hdrs)
  File "urllib2.py", line 425, in error
    return self._call_chain(*args)
  File "urllib2.py", line 360, in _call_chain
    result = func(*args)
  File "urllib2.py", line 506, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)

It's possible this is a port configuration problem? If yes (...or if not)
how can I solve it?
Thanks in advance, alessio
