[mapserver-users] WFS GetFeature issue with MS4W

[Eric Lemoine]

Hi

I'm facing an issue with WFS GetFeature POST requests. This is with
MS4W 3.0.4 [1] (installed from the zip file), on Windows Server 2008
R2 Standard, 64-bit.  The XML response returned by mapserv is
incomplete. The WFS GetFeature request is pretty basic, it just
includes a BBOX filter, see [2]. The end of the truncated response
looks like this:

<gml:featureMember>

        	</gml:Box>

The same WFS GetFeature using GET results in a complete response, so
the issue really is related to POST. And when using MapServer on
*Linux* the same exact WFS GetFeature does result in a complete
response. On Windows the response headers include Transfer-Encoding:
"chunked". This has sounded suspicious to me first, because on Linux
MapServer does not return chunked responses. But I also get
Transfer-Encoding: "chunked" on Windows when using GET.

I have enabled debugging logs in MapServer [3], but this hasn't led
anywhere - the MapServer log file remains empty. Apache access.log
includes "Apache access.log: nesitnd1.ne.ch - - [23/May/2012:12:28:19
+0200] "POST /test_eric/mapserv? HTTP/1.1" 200 36825". This is
interesting to note that the response is a 200. And Apache error.log
does not reveal any MapServer crash (no "premature end of script" type
of thing).

Any suggestion for me?

Thanks.
