Thank you. <br>
Interesting remark you make on the WMS-spec. Never thought of
that.<br>
You say that I can add a config option to return something other
than 200. I suppose by that you mean that such a config option
does not exits, but that I can hack it in?<br>
<br>
Can you please elaborate a bit on how non 200 status codes on
service exception reports could break a client. No map is no map?<br>

<div>It's the WMS spec itself that requires 200 response codes.
You can hack the code or even add a configuration option to
return something other than 200, but you'll risk breaking your
clients. Also note that checking for specific text is not
going to work all the time, as the client can request an
"inimage" exception text, i.e. returned as pixels in a png
image.</div>
