Wow, thanks.<br>
Would you mind adding it to the CodeSamples?<br>
<br>
For the IIS on XP problem, try this:<br>

here is a simple <a href="http://ASP.NET" target="_blank">ASP.NET</a>
ashx to server MapGuide Tiles Directly.<br>
<br>
It' different from the one found on "<a href="http://trac.osgeo.org/mapguide/wiki/CodeSamples/Tiles/ServingTilesViaHttp" target="_blank">http://trac.osgeo.org/mapguide/wiki/CodeSamples/Tiles/ServingTilesViaHttp</a>"
because it doesn't require any web server configuration.<br>
The only point is to use my ashx as a proxy to MapGuide.<br>
Testing would be nice. If it's all OK, and someone wants to post it on
wiki... or translate in PHP...<br>
BUT don't test it with a non server OS. For example in WindowsXP I get
lot of empty tiles. This is not the case with Windows Server 2003.<br>
REMINDER FOR ME: don't loose time! Test on real server OSs!<br>

[OFFTOPIC] A suggestion about MapGuide Installer -<br>
<br>
it would be nice that besides the installer, there was a zipped archive
with the installed files, to give the possibility of manually
installing MapGuide without running an installer. This could be clearly
set to UNSUPPORTED, and that no help would be given in the list to who
desires to use the zipped archive.<br>
<br>
This is because, in my opinion, one cannot understand the system, if
not by using a manual install. It's the path I followed when I for the
first time used MapGuide. <br>
<br>
To provide such a thing is very simple: install in C:\OsGeo, zip folder
and publish in "<a href="http://mapguide.osgeo.org/download" target="_blank">http://mapguide.osgeo.org/download</a>".
Only for windows, linux always needs compilation because of different
shared objects between distributions.<br>
<br>
At this point one can extract the zip wherever she wants, change ini
files, set virtual directories, enable PHP, change folder permissions,
and the game is done!<br>
