<p>Hi,<br>
</p>
<p><br>
</p>
<p>I am working on a local OSM WMS service (provided by mapserver). I want to cascade this & use it within other servers/maps. And advice appreciated.<br>
</p>
<p><br>
</p>
<p>I have set up a simple mapfile to do this, but keep getting a "cannot calculate extent" error that I cannot explain or resolve. I think the error is from my service, and not the one being cascaded.
</p>
<p><br>
</p>
<p>The underlying services (in different styles) can be viewed in a browser at:</p>
