<!-- Default configuration options for the Backload component. Insert only the settings you want to change in your Web.Backload.config file.
    // Remarks: The server side Backload handler supports very fine granulated and complex storage structures (folders and database tables).
    // These storage structures can be influenced server and client side. On the server side you can set up root folders (web.config), on the client you set up context specific subfolders (see example below).
    // The good thing: You do not have to use all this stuff. Just omit these settings to use the default simple and flat structure. Everything is stored withing the ~/files folder by default.
    // Client side parameters: objectContext and uploadContext (see Example):
    // The parameters objectContext and uploadContext are optional. You do not have to include them in the request.
    // Basically they influence the storage location on the server, regardless if it is a database or folder structure.
    // Server side settings: filesRoot, objectsRoot and content type specific subfolders:
    // filesRoot is the root folder for all uploads. objectsRoot is a subfolder an can be ommitted if you do not need it.
    // Set up content type specific sub folders, if you want to filter and store files of a specific content into separate subfolders. Example: Store images into an images subfolder (content-types: images/jpeg, images/png, etc. typeFragment: images/). See also example in the contentTypes section.
    // Example:
    // You want to set up an artist library were users are able to store content (songs, images, videos, other files).
    // You want to store the different content in separate subfolders of a root artist folder, where any content belonging to this specific artist is stored.
    // Your servers folder structure: [filesRoot]/[objectsRoot]/[objectContext]/[uploadContext] (e.g. ~/files/artists/michealjackson/videos) where [filesRoot] and [objectsRoot] are set up server side in the web.config.
    // The objectContext will be the artist. It must be a unique name (e.g. michealjackson) or id. Any uploaded files related to this artist will be stored within a location of this unique id or name.
    // UploadContext values are the different content types in this example (e.g. songs, images, videos, other) and result into a subfolder or different datatable. 
    // If you use separate client side upload controls for the different content, you can simply include hidden input fields. The client jQuery File Upload control will automatically transmit hidden input files to the server. But if you manually perform a ajax request, you have to set these parametes by hand. 
    // objectContext, uploadContext and fileName can be send in the url as a querystring or in the body (form).
    // Note: The subfolder structure can be even more complex: uploadContext supports subfolders within subfolders (e.g. /songs/mp3, /songs/wav, etc.). Simply separate the subfolders by semicolon. Use this example pattern as the value of uploadContext: value="songs;mp3" or value="songs;wav". 
    // Note also: You can also set up a content type specific subfoldering on the sefrver within the web.config (examples).

	  // NOTE: This file is not intended to be used directly. Copy the relevant parts to your web.Backload.config file and make your settings in that file.
	  //		 The settings in this file are the default values. You do not need to set this values agein. See Example 01 on Github.
