Hi Phil, Thanks again for your guidance. I am bit confused when you said,
have a proxy page INSIDE YOUR APPLICATION - ie in the same directory as your page or in a subdirectory below it. Did u mean that I should have my py script to which I making the AJAX request in the same dir? Then I already have. Only issue is that, the script is running on port 9000 ( http://128.196.142.94:9000/info?lat=53.33935546875&lon=-121.99951171875). So the domain is same but the ports are different. check that the passed URL is reasonable for the application to call I was able to call py script url (wget " http://128.196.142.94:9000/info?lat=53.33935546875&lon=-121.99951171875"; -o test.1.log -O test.1), u can run this on terminal and it should fetch you the JSON. So, after this, how should I complete the other two parts? 2/ Open an http connection to the passed page 3/ pipe the page content as output.
