<p class="MsoNormal">You cannot directly control what the browser chooses to cache but you can use mod_expiry and friendly-reusable URLs (like XYZ tiles) to help in that cause. Repetitive WMS requests will be caught by the cache but it's much harder to get
a hit as it will change when the screen size, resolution, or small shifts in locations differ.<u></u><u></u></p>

<p class="MsoNormal"><span lang="EN-US">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></span></p>
