qix files

[Gaston Izaguirre]

Marcos,

Check your mapfile for the definition of your vector layer:
Shapefiles are native to MapServer, and therefore do not require the .shp 
extension in the DATA path of the LAYER.

In fact, in order for MapServer to use the .qix extension you MUST NOT 
specify the extension, for example:

LAYER
  ...
  DATA us_states    #MapServer will search for us_states.qix and will use it
  ...
END

LAYER
  ...
  DATA us_states.shp    #MapServer will search for us_states.shp.qix and 
won't find it
  ...
END

Saludos,
Gaston.
