Abstract: In particular embodiments, a client computing device identifies a USB device connected to the client computing device. The client computing device redirects the USB device to a remote server computing device. The client computing device determines whether the USB device is of a particular device type, and if the USB device is determined to be of the particular device type, then the client computing device requests data from the USB device. Upon receiving a response from the USB device comprising data, the client computing device sends the data to the remote server computing device.

Abstract: In particular embodiments, a server loads in a browser a webpage including flash content including an ActionScript, the ActionScript including at least one function. The browser loads a flash redirection plugin and requests the plugin to execute the ActionScript. The plugin determines whether a cache at the server includes the function, and if the cache includes the function, the plugin determines a result associated with the function in the cache and returns the result to the browser.

Abstract: In one embodiment, a method includes, by a computing device, receiving identifiers of one or more sessions, users, or groups selected to have access to a particular redirected device. The computing device stores the identifiers in a database, receives a request associated with a session, user, or group to access the particular redirected device, and determines whether an identifier for the session, user, or group associated with the request is stored in the database. If the identifier is stored in the database, then the computing device grants access to the redirected device, or if the identifier is not stored in the database, then the computing device blocks the session, user, or group from accessing the redirected device.

Abstract: In particular embodiments, a client loads a flash player. The flash player requests a flash redirection browser to execute an NPN call, the NPN call including a string. The flash redirection browser determines whether a cache at the client includes the string, and if the cache includes the string, the flash redirection browser determines an identifier associated with the string in the cache and returns the identifier to the flash player.
