[flexcoders] HttpService post error 2032:iostream error

[longxjyh]

When I use HttpService to send data by post method,I encounter a 
problem.I find if the length of the post data is over 1022,then flex 
rises the runtime error 2032.However the data is sended to server 
wholelly and the server has accepted all the data without any error.I 
can't understand why flex rises such error.The problem exists only in 
IE.In firefox ,it's ok,no problem.
