If you wish to set a cache for the generated images so that they
are not dynamically recreated every time, specify a default CacheFolder here.
The Cache Folder is an absolute folder location relative to the root of the
QCubed application. So for example, if you have the QCubed application installed
at /var/web/wwwroot/my_application, and if docroot is "/var/web/wwwroot" and if
you therefore have a subfolder defined as "/my_application", then if you specify
a CacheFolder of "/text_images", the following will happen:
Cached images will be stored at /var/web/wwwroot/my_application/text_images/...
Cached images will be accessed by
Remember: CacheFolder must have a leading "/" and no trailing "/", and also
be sure that the webserver process has WRITE access to the CacheFolder, itself.
