     * For example, if the URL is /product/myproductimage.jpg, then the MD5 would be
     * 35ec52a8dbd8cf3e2c650495001fe55f resulting in the following file on the filesystem
     * {assetFileSystemPath}/64/a7/myproductimage.jpg.
     * 
     * If there is a "siteId" in the SparkRequestContext then the site is also distributed
     * using a similar algorithm but the system attempts to keep images for sites in their own
     * directory resulting in an extra two folders required to reach any given product.   So, for
     * site with id 125, the system will MD5 "site125" in order to build the URL string.   "site125" has an md5
     * string of "7d905e85b8cb72a0477632be2c342bd6".    
     * 
     * So, in this case with the above product URL in site125, the full URL on the filesystem
     * will be:
     * 
     * {assetFileSystemPath}/7d/site125/64/a7/myproductimage.jpg.
