Hello,<br>
<br>
If you are using a recent version of PROJ.4, you should be able to
use epsg:3857 for Web Mercator. MapServer can reproject your data
on-the-fly if you also have projection blocks in your layer
definitions to say what projection the data are (i.e. epsg:4326).
This will slow down the map draws somewhat, so if you are planning
to always display this map in Web Mercator, it's a good idea to
reproject your shapefiles.<br>
<br>
... oh, it looks like Jeff beat me to it :)<br>

<div>Hello everyone,</div>
<div> I've been using shp2img tools to generate tile
image by mapfile. And the project is by default,which is
epsg:4326.Now I want to use Web Mercator Projection,Can
you tell me how to write the mapfile's projection
label?And Do I need to change my shpfile's projection?</div>
<div> Waiting for your answers,thanks very much!</div>
