javascript - POST max length or JS object max length? -


i stuck annoying problem. have application on google app engine sends data (formatted json string) js through post php page. when select more specific amount of data, nothing returned. tried increase post_max_size 20m, not better. limitation here? there possibility data js php? tried this:

function openwindowwithpost(url, name, keys, values) { var newwindow = window.open(url, name);  if (!newwindow)     return false;  var html = ""; html += "<html><head></head><body><form id='formid' method='post' action='"         + url + "'>";  if (keys && values && (keys.length == values.length))     (var = 0; < keys.length; i++)         html += "<input type='hidden' name='" + keys[i] + "' value='"                 + values[i] + "'/>";  html += "</form><script type='text/javascript'>document.getelementbyid(\"formid\").submit()</sc"         + "ript></body></html>";  newwindow.document.write(html); return newwindow; } 

you possibly check server configuration file php.ini , check maximum post size max_post_size. if default post string length isn't enough, increase it's length.
