Ajax using https on an http page

My site uses http and https protocol; it doesn't affect the content. My site uses jQuery ajax calls, which fills some areas on the page, too.

Now, I would like to do all ajax calls over https. (please dont ask me why :)) When I am on a page with https protocol, ajax requests are working. When I'm on a page with http protocol, I get a javascript error: Access to restricted URI denied

I know that this is a cross domain problem (in fact, it's a cross protocol problem), and I know that I should use the same protocol in ajax calls as on the current page.

Still, I want to all ajax calls to be https, and call them on a page that was served over http. Is there any workaround to achieve this (some json/proxy solution?), or is it simply impossible?

Try JSONP.

most JS libraries make it just as easy as other AJAX calls, but internally use an iframe to do the query.

if you're not using JSON for your payload, then you'll have to roll your own mechanism around the iframe.

personally, i'd just redirect form the http:// page to the https:// one

http://example.com/ may resolve to a different VirtualHost than https://example.com/ (which, as the Host header is not sent, responds to the default for that IP), so the two are treated as separate domains and thus subject to crossdomain JS restrictions.

JSON callbacks may let you avoid this.

You could attempt to load the the https page in an iframe and route all ajax requests in/out of the frame via some bridge, it's a hackaround but it might work (not sure if it will impose the same access restrictions given the secure context). Otherwise a local http proxy to reroute requests (like any cross domain calls) would be the accepted solution.
