		<description><![CDATA[In the code snippet where you list all the headers you had to set specifically for IE, you don&#039;t say in what file you put those.  It looks like it&#039;s in a Rails action, since you&#039;re saying render :nothing =&gt; true, or possibly a before_filter, but then you mention using X-Accel-Redirect in Nginx to serve the files directly.  Can you please clarify? I&#039;d like to implement this.

Thanks!]]></description>

		<description><![CDATA[That&#039;s great to hear!  I thought that the switch to HTTPS might have been slightly bandwidth intensive as proxy caching, etc. cannot be used anymore. So I was thinking that using a signed request instead of HTTPS everywhere might also work e.g. this is how Amazon AWS does it http://aws.amazon.com/articles/1928#HTTP (assuming that the secret key was transferred to the client over SSL and stored locally)

But if the impact of using HTTPS is negligible, best to stick to that I guess.]]></description>

		<description><![CDATA[I will admit I didn&#039;t read all the details above, but I did notice that you suggest having a site have some parts SSL and some parts non-SSL. Doesn&#039;t that expose the cookies to session hijacking in the non-SSL part of the session? This is supposedly a vulnerability of some sites that are susceptible to firesheep, even though SSL appears to be enforced throughout the session.]]></description>
