Have a read regarding TILEINDEXes
(<a class="moz-txt-link-freetext" href="http://mapserver.org/optimization/tileindex.html">http://mapserver.org/optimization/tileindex.html</a>). It may be
useful to have one TILEINDEX (and one layer) per scale group (so a
total of 6 layers). The TILEINDEX will provide a spatial
limitation [min/max x/y] per file.<br>

<p class="MsoNormal"><span lang="EN-US">I was thinking that I
only shall use max scale, not min scale, because if I don’t
have a chart with a larger scale a certain position when I
zoom in, then I shall at least see a chart. Even if has a to
small scale for this zoom. I don’t have any spatial
restrictions on each layer or layer file, just for the map
file -90, -180, 90, 180 (i.e no limits)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is it possible to have
