[=?GBK?B?utXQ/rvd?=]

I has wrote a mapfile. It can be published successfully with openlayers. But its speed is very slow. So I try to use tilecache to improve the speed.
now I have install  the tilecache, and it can run with the example.But it doesn't run with my mapfile. Here is the program
[road]
 type=WMS
 url=http://localhost/cgi-bin/mapserv.exe?map=/ms4w/Apache/htodcs/file/jia1_test.map&transparent=true&
    layers=build,street
 extension=png
 bbox=-180 -90 180 90
 maxResolution=0.0439453
 srs=EPSG:4326
 level=20


the html as follow:
layer = new OpenLayers.Layer.WMS( "global", 
                    "http://localhost/tilecache-2.10/tilecache.py?",
{layers: 'build,street', 
format: 'image/png' } );
            map.addLayer(layer);


Anyone can help me,thanks!!!
