Hi and sorry for the vague subject line. Here is the situation. On one page of the site an iframe is rendered. The src element of the iframe is a local url. The src url will render an html page which is simply an html form that posts to a remote url. The remote site will do some internal posts and then finally sends a get request back to my app. The final step is to render a local page from my app. All that should happen within the iframe. With Firefox the final page is not rendered. I can debug the site and I see the final get request is processed on the server but Firefox doesn't display the page. I've tried returning a redirect to the final page instead of returning the html and then I can see in the dev tools a get request to that (local) url however I just get a blank page in the iframe. All this is using https urls. Any suggestions are appreciated. Thanks. Sean
