[Tilecache] Increase WMS request timeout?

Tue Nov 25 01:08:53 EST 2008

Chris,

You can just go into your site-packages (likely where python setup.py  
installed the egg) and remove the whole egg which is just a folder of  
the scripts that is automatically on your PYTHONPATH.

This one: 'TileCache-2.04-py2.5.egg'

Then to get the imports working, download a fresh copy of tilecache to  
an easy to work with location, and simply put the folder that contains  
the 'TileCache' folder on your PYTHONPATH by setting that variable in  
your System Settings.

The you should be able to do:
 >>> import TileCache

and then with mod_python use the directive:

PythonPath "['/path/to/folder/containing_tilecache/'] + sys.path"
