Hi Arnd, Chris<br>
<br>
<br>
Okay, so OpenLayers always does default url encoding on the request.
This goes wrong if the encoded request string is redirected.<br>
So<br>
1 (direct)<br>

does not work<br>
<br>
<br>
I don' see why urlencoding has to taken place. This might be necessary
only if a proxy was set.<br>
I suppose Arnd is right about his suggestion that OpenLayers should not
encode the request. It's much like setting an <IMG SRC /> isn't
it.<br>
You might add javascript's unescape() function instead of removing the
OpenLayers.Util.getParameterString.<br>
<br>
How about a setting: mylayer.encode = false;<br>
Or rather, not encode at all unless explicitly said:
mylayer.encoding=true<br>
<br>

uest=getcapabilities&service=wms delivers the map.
>From WMS specification 1.1.1:
6.2.1 Reserved characters in HTTP GET URLs
The URL specification [IETF RFC 2396] reserves particular characters as
significant and
requires that these be escaped when they might conflict with their defined
usage. The
present WMS specification explicitly reserves several of these characters
for use in the
query portion of HTTP GET requests. When the characters "?", "&", "=", "/",
":" and ","
appear in one of the roles defined in Table 1, they are to appear literally
in the URL.
When such characters appear elsewhere (for example, in the value of a
parameter), they
are to be encoded as defined in [IETF RFC 2396].
This means the OpenLayers API is wrong to encode image/png or EPSG:4326 etc.
