Hi Prasad,
Try changing your data to output the name of the value you are POSTing
first.
Your server won't know what the parameter is called otherwise...
eg:
Connect...
POST /servlet/myTest HTTP/1.0\r\n
Content-type: text/html\r\n
Content-length: 17\r\n
\r\n
>> server says: HTTP/1.1 100 Continue
>> server says: Server: Microsoft-IIS/4.0
>> server says: Date: Sun, 04 Apr 1999 11:22:04 GMT
myparameter=hello
