no, browse means an old non-ogc-method of requesting maps from 
mapserver, nothing to do with internet browser 
(http://www.mapserver.org/mapfile/template.html). Usually you get this 
message if any WMS-request-parameter is missing, so mapsverver cannot 
identify your request as a wms-request. Might be the 'SERVICE=WMS'.

let php echo the whole request, you will see what is missing.
