Render app proxy response without layout by Andrew

Hello,

I am using Application Proxies in my Shopify app and have run into an interesting issue.

I have a need to render the liquid from certain application proxy responses in the store without using the default store layout.  To do this my server is returning a liquid template to shopify that starts with

{% layout none %}

however it seems that for application proxy responses this is ignored and the page is still rendered in the default layout.

Is there anyway to render an application proxy response without a layout?

Thank You,

-Andrew
