There is an API endpoint which streams results as it gets them. E.g.:

GET /results HTTP/1.1

HTTP/1.1 200 OK
Content-Type:test/plain
Content-Transfer-Encoding:chunked

C;
{"foo":"bar"}
...10 minutes later...
D;
{"bar":"baz"}
0;

Is there any way to get {"foo":"bar"} before without waiting ten minutes for the rest of the page to be sent?>

Yes, by using COMET for example http://en.wikipedia.org/wiki/Comet_(programming) – antyrat Jul 29 '14 at 16:12
@antyrat thats the general name of the idea, but nowhere in that link does it tell me how to implement it in a way that is compatible with this type of endpoint – chacham15 Jul 29 '14 at 16:17

@antyrat all of those examples wait for the entire request to be fulfilled before returning the result. – chacham15 Jul 29 '14 at 16:22
Not with jQuery afaik. – Bergi Jul 29 '14 at 16:23
@Bergi is there a way without jQuery? – chacham15 Jul 29 '14 at 16:23
You can create hidden iframe and check it periodically w/ content's. – antyrat Jul 29 '14 at 16:24
