Hi,
 
the problem is the encoding of the FORMAT and SRS values with OL 2.5
 
This works not:
http://milntj34.rivm.nl/wmsconnector/com.esri.wms.Esrimap/schiphol2005_a?VER
SION=1.1.1
<http://milntj34.rivm.nl/wmsconnector/com.esri.wms.Esrimap/schiphol2005_a?VE

Changing the FORMAT value 

Response:
<ServiceExceptionReport version="1.1.1">

Changing the SRS value 
works:

IGHT=256

With OL Version 1.0 the WMS works all right.
 
Looking at the code I don't find where the encoding takes places. Where I
have to look?

Hi,

The capabilities of 

http://milntj34.rivm.nl/wmsconnector/com.esri.wms.Esrimap/schiphol2005_a?req
uest=getcapabilities
<http://milntj34.rivm.nl/wmsconnector/com.esri.wms.Esrimap/schiphol2005_a?re
quest=getcapabilities&service=wms> &service=wms 

return a OnLineResource like

  <OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="http://milntj34.rivm.nl:80/wmsconnector/com.esri.wms.Esrimap/sch
iphol2005_a?" xlink:type="simple" />

Using this we discover that this server redirects this to another server
(leaving the requests intact)

http://mapserver.mnp.nl

So from the capabilities  i create the OpenLayers Layer using
milntj34.rivm.nl: but then i get no image. 
Is a redirect not expected by OpenLayers?
