I'm making a post to my servlet (the servlet works with a url get, and via jquery), I can't figure out where my error is in how my headers are written. The server isn't getting the payload "content"... thanks for your help.
The server returns 200, and I'm getting through I'm just not getting my "value=********"

int status = WL_IDLE_STATUS;

// use the numeric IP instead of the name for the server:

// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
