<p class="MsoNormal">Hello,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Using Apache, I would like to know if it is possible to set up a browser cache for images from mapcache so that images are stored on the client machine instead of having to get resent from the server. I enabled mod_expires and noticed
that the png files for the buttons are cached unfortunately the mapcache png files are not cached. I presume it might not be possible to cache images from mapcache when used in WMS mode, but it might be possible when using either WMTS, or TMS mode.<u></u><u></u></p>
