[mapserver-users] mapcache returns error 400 bad request

Tue Mar 19 11:35:49 PDT 2013

Stephen,

do you have an explicit example, please?
Does it mean i have to do apache url rewriting?

my mapcache source tag is it correct? :

<source name="monserv" type="wms">
     <http>
          <url>http://localhost/cgi-bin/mapserv?</url>
     </http>
     <getmap>
        <params>
            <FORMAT>image/png</FORMAT>
                <LAYERS>dep_point_pop</LAYERS>
                <MAP>/var/www/mapfile/dep_point.map</MAP>
        </params>
    </getmap>
</source>

The point that Thomas is making is that mapcache understands WMS 
requests NOT mapserver cgi requests

http://localhost/mapcache?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&layers=test&mode=map&map_imagetype=png&mapext=-135+0+-90+45&imgext=-135+0+-90+45&map_size=256+256&imgx=128&imgy=128&imgxy=256+256

This does not work because it is not a valid WMS request.

If you go to the demo page for the WMS service, and view source, then 
you can see how to setup a OpenLayers to talk to mapcache.

In FF, if you right click on the map, and select view image, you will 
see what the url for the image or tile looks like.
