Methods and systems for facilitating content accessibility via different communication formats are provided. According to one embodiment, information indicative of one or more communication formats via which a client device is capable of communication is stored on a client device by (i) sending the client device a web page having embedded therein test content associated with a first protocol stack and/or a second protocol stack; and (ii) based on a response to the test content received from the client device, determining communication capabilities of the client device. A result of the determination is stored within a browser cookie, which is sent to the client device. A content request is received from the client device that includes the browser cookie. The client device is redirected to a server device appropriate for the communication capabilities of the client based at least in part on the browser cookie.
