javascript - No auto-decompression of gzipped json on browser's side when using angular's http get method - Stac

I'm trying to load a json file using angular (v1.2.6):

$http.get('myfile.json').success(function(data) { ... }

This works fine, except when I create a (static) pressed version of the file on the server, and try to load 'myfile.json.gz' instead (to reduce the loading time).

The request headers seem correct (Chrome 31.0 on Mac) (as stated here and here):

Accept: application/json, text/plain, */*
Accept-Encoding: gzip,deflate,sdch

while the response headers contain:

Connection: close
Accept-Ranges: bytes
Content-Length: 702468
Content-Type: application/x-gzip
Content-Encoding: gzip

However, the content is not automatically depressed by the client browser, as I understand it should be. data.length is ~700Kb instead of the original unpressed ~3Mb.

Although this one post suggests it needs to be done manually, I understand depression should be automatic and transparent.

My question is, should it be depressed automatically? and why isn't it the case here?

Your content type should not be "application/x-gzip* it should stay : application/json

The content encoding is enough to say to the browser that the content is zipped.

What HTTP server are you running ? You should configure it in order to return the correct mime type, regardless of the .gz extension.
