Bulk tracking HTTP syntax problem (2 replies)

Hello,
I am hard time getting bulk tracking over HTTP, posting to piwik.php, to work. I just take 3 of my regular requests (that work fine by themselves) and create a string using the syntax described at [developer.piwik.org], and them POST it to piwik.php:

http://MYURL/piwik.php{"requests":["?idsite=6&rec=1&_id=0000000051B49013&url=http://MYURL/App%20Open&ua=Mozilla/5.0%20(Macintosh;%20Intel%20Mac%20OS%20X%2010_10_1)","?idsite=6&rec=1&_id=0000000051B49013&url=MYURL/open&e_c=Operating%20System&e_a=Mac&e_n=10.10.1&e_v=1","?idsite=6&rec=1&_id=0000000051B49013&url=MYURL/open&e_c=OEM%20Software&e_a=Aion&e_n=Mac&e_v=1"],}

I substituted the real url for MYURL in the above example.

This is how I understand it should be constructed. When I try it in a browser (normally I send it from desktop app), it takes me to All Websites Dashboard, with no effect on the stats. I get no errors from debug.

I also tried it with "?" after piwik.php - same result.

I'm sure it's something silly. Any ideas?

Thank you.
