[mapserver-users] WFS GetFeature issue with MS4W

[Jeff McKenna]

Hello,

Actually this is a sporadic problem (difficult to duplicate) that has
existed for a while it seems, and has appeared on Windows and Linux.
Here are some related open tickets, please join the discussions there
and provide feedback:

> I'm facing an issue with WFS GetFeature POST requests. This is with MS4W
