[mapserver-users] Corrupted zipped shapefiles from WFS

[Jeff McKenna]

Hi Keith,

I know for a similar issue I created a small test case posted to a 
ticket last week 
(http://trac.osgeo.org/mapserver/ticket/3751#comment:21) and in that 
case I was able to output a valid zip archive of a shapefile through a 
WFS GetFeature request on Windows.  If I remember correctly I had to use 
MapServer trunk to get this to work properly.

Honestly I didn't dive far into if the zips were valid or not (come to 
think of it, I was always using 7-zip to open them as well, which worked).
