Hi Mark Thanks for the reply. But I am already putting the projection information in three places arent I?
MAP PROJECTION "init=epsg:27700" END WEB METADATA "http://localhost/cgi-bin/mapserv.exe?map=example.map&"; WMS_SRS "EPSG:27700 ESPG:4326" END END LAYER NAME "layer" CONNECTION "http://externalwmshost/&"; CONNECTIONTYPE WMS METADATA "wms_srs" "EPSG:27700" END END The external WMS only supports 27700 - thats why I want to reproject in my mapserver instance. Any other clues?
