Description
From http://logs.qgis.org/slogs/%23qgis.2006-03-22.log:
"morb_au, I tested your proxy thing but it seems to forget user & pwd as soon as you close the connection setup box"
The error is possibly in QgsHttpTransaction or QgsServerSourceSelect.
Will either need to fix this up before 0.8 or hide the user/pass feature from the GUI until fixed for a future release.

Speculative fix in 07a42c17 (SVN r5698).
Can somebody please test with a proxy for me and report back, or build a Windows version for me so that I can test?

With SVN 07a42c17 (SVN r5698), access to a wms server through a proxy now works for me. I get a list of available layers, but never get an image. The Metadata tab in the resulting layer properties dialog has no text in the value column. It works fine without a proxy in place.

Brendan,
The problem here is that the wms provider does not have the proxy information set. The temporary wms provider instance created in the qgsserversourceselect class has the proxy stuff set correctly, but the second instance of the wms provider that is created in the QgsRasterLayer class doesn't (and is the one that retrieves the actual map data). The layer data that is passed to the QgsRasterLayer constructor doesn't include the wms proxy information, so the provider uses it's defaults.
This patch shows what needs to be set, but it's just a hack to confirm that it solves the problem (which it does):
Index: qgsrasterlayer.cpp
===================================================================
--- qgsrasterlayer.cpp (revision 5709)
+++ qgsrasterlayer.cpp (working copy)

+ pp->setProxy("www-proxy",80,"","");
+
dataProvider->addLayers(layers, styles);
dataProvider->setImageEncoding(format);
dataProvider->setImageCrs(crs);
This patch just hard-wires the proxy information for all raster layers to the required settings for the proxy that I have acccess to. Obviously, it should really get the information from one of the parameters that is passed to the QgsRasterLayer constructor.

Potential fix in d04ea690 (SVN r5716) based on Gavin's comment of 08/19/06 06:33:52. Please have a test of it if possible and report back.

More changes in SVN c14a0207 (SVN r5724) that should fix the problem. Needs a bit of testing though...

Seems to work fine now. Tested both with and without a proxy.

Hi,
proxy works now, great & thanks.
But strangely you have to add 'http://' into
the WMS URL (while not needed elsewhere).
It would be great if it worked without 'http://'
in the WMS URL as well (for consistency).
Great job,
Markus
