Public Methods

Method	Description
AddImageToCacheAsync ( Stream stream, string contentType ) : System.Threading.Tasks.Task	Adds the image to the cache in an asynchronous manner.
AzureBlobCache ( string requestPath, string fullPath, string querystring ) : System	Initializes a new instance of the AzureBlobCache class.
CreateCachedFileNameAsync ( ) : Task	Gets a string identifying the cached file name.
IsNewOrUpdatedAsync ( ) : Task	Gets a value indicating whether the image is new or updated in an asynchronous manner.
RewritePath ( HttpContext context ) : void	Rewrites the path to point to the cached image.
TrimCacheAsync ( ) : System.Threading.Tasks.Task	Trims the cache of any expired items in an asynchronous manner.
