The issue is that I am trying to send XML inside the URLVariables, but seem to be encountering a size limit, when reached the request fails, and never makes it to back end. I am using AIR, but I think both have same issue. There is no documentation about any size limit, but it is pretty clear that one exists. Any ideas?
var request:URLRequest = new URLRequest("http://www.xx.yyy");
var variables:URLVariables = new URLVariables();
variables.searchData = xml.toString();
variables.reportType = "excel";
request.data = variables;
request.method = URLRequestMethod.POST;
Did you find out any info about the size limit?
