Loading external content into div withinout iframe

I have a website that has used an iframe for a long time to display external content within my page.   As of recently, the external website has enabled x-frame-headers that blocks us from using an iframe.   I am trying to find a way to use ajax to request a local page on my server that redirects to the external page and then loads into a div tag.   Number one I dont know if this is possible, but the issue I am having thus far is that i cant seem to capture the data of the redirected page.    I see a status 302 code from within the google chrome console, but I cant seem to find a way to get that content.   Can anyone offer assistance?  I would greatly appreciate it.  I am using a tomcat server with a jsp environment.
