Thomas,
Thank you.
Interesting remark you make on the WMS-spec. Never thought of that.
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?
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?

Marco,
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.

Finding and modifying status codes
I'd like to find out (and maybe modify) the HTML status codes
mapserver
attaches to a WMS service exception report.
I deploy mapserver behind Nginx with supervisord as a fastcgi
provider and
process manager. Nginx does caching of responses on getmap requests.
As I don't want Service Exception reports to be cached I've added a
directive to the Nginx config not to cache error documents containing
'serviceException'.
This is not working properly, I think because nginx only regards a
response
as an error when a non-200 status code is attached.
So I'm trying to find the status codes mapserver attaches to a
response.
If I do from command line mapserv7
QUERY_STRING="map=my.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&....(rest
of valid wms request)" I see the headers (and the png) when te
request leads
to a response containing a map.
If I do the same with a request that generates an service
exception report I
get back error messages instead of the response I see in my browser.
So, how to find out the headers of the response before it goes trough
supervisord an nginx?
Or does anyone know what status code the header contains?
And the million dollar question: can we stick a 500 status code
header on
the response if it's not there?
Any help greatly appreciated, MArco
