Another strange thing with GDAL WFS driver. Earlier it did not try to
access the HEAD of a XXX.resolved.gml and now it does:
Here's an excerpt from my server logs. These calls are created by GDAL,
the first is a good GetFeature call, which gets 215633 bytes of GML and
the next is bogus. I can see this made up in ogrgmldatasource.cpp but do
not understand why. In February this did not happen and GDAL parsed the
GML the WFS provided fine (it actually created by GDAL too).

Ari,
I don't remind a recent change that might have affected this (but my memory can
be fragile), but reviewing the GML driver code, the fact that .resolved.gml is
probed means that the GML driver doesn't recognize the first bytes of the
GetFeature response to be a GML WFS document. Could you paste them ?</pre>

It seems to be in ogr (it's made by GDAL). I'll try changing that.<br>

Does the probing of .resolved.gml, apart from slowing down the process, prevent
the driver to parse the GetFeature document ?</pre>
</blockquote>
<br>
yes, the resolved.gml is not older than the GetFeature doc, thus it
is used and found to be empty. I commented that out but it still
can't parse the features.<br>

<pre wrap=""> I think it should not, but there
might be subtle issues since it will probably not use the schema obtained with

<br>
It is using the schema it got from DescribeFeature.<br>

About the OpenSSL problem. I can probably bypass it by using only
Curl (there are Perl bindings to Curl)<br>
