<div>WMS through your local intranet is very fast, and its a way to scale up your mapping application horizontally, splitting the load between servers if the layers are processing intensive to draw.</div>
<div> </div>
<div>I've never tried WMS to localhost before, but assuming you can do that it should be even a little faster. Perhaps not as fast as just having the layers within the mapfile in the usual manner, but much faster than WMS accessing a remote server on the internet. I'd lean to this idea for your situation.
</div>
<div> </div>
<div>Another way which would likely be overkill for your needs would be to create a system like what the guys at NRCan have done, creating a database application that creates the mapfile on the fly. I heard that for them it has eliminated the need to update thousands of map files when switching to new versions with syntax changes etc, or for making small symbolization changes that effect many map files.

<div>I do like the 'includes' idea. It would be great for those of us in between the extremes.</div>

<br>><br>> Is there any syntax for including the contents of another file in a<br>> mapfile?<br>><br>><br>><br>> I have about 60+ layers that need to go online and most of them fall<br>> into fairly clear groups of five layers each. Based on their
<br>> selection in a drop-down list, users will indicate the group of maps<br>> they are interested in looking at and the application will load that<br>> map file. There are, however, about 10 ancillary layers of data that
<br>> should be available no matter what map is loaded (roads, hydro,<br>> cities, etc.). Rather than repetitively defining this information in<br>> every map file, is there any way I can define the ancillary layers
<br>> in one file, and then simply load that file's contents from within<br>> the other map files?<br>><br>><br>><br>> I'm not sure what to call these except "includes." I haven't had any<br>
