I have a client application (iPhone) that collects 10,000 doubles. I’d like to send this double array over HTTP to an appengine server (java). I’m looking for the best way to do this.

Best can be defined as some combination of ease of programming and compactness of representation as the amount of data can be quite high.

My current idea is that I will convert the entire array of doubles to a string representation and send that as a POST parameter, on the server parse the string and convert back to a double array. Seems inefficient though…

Thanks!

    I guess that there are lots and lots of different ways to do this. If it were me I would probably just serialize to an array of bytes and then base64 encode it, most other mechanisms will significantly increase the volume of data being passed.
