Microsoft azure table authentication stringtosign error

Question

I am having a problem with `stringtosign` authentication for azure table pagination query.
This is the current `stringtosign` im using :
    GET\n\n\nFri, 05 Sep 2014 03:57:11 GMT\n/mystorageaccount/mytablename\nNextPartitionKey:1!20!UmFjZSBNZW1iZXJfNA--\nNextRowKey:1!12!TmFtZV85ODE-
Is there anything wrong with this `stringtosign` authentication?
The rest of the Headers are exactly the same as Fiddle. 
**Example**
    GET /mytablename?NextPartitionKey=1%2120%21UmFjZSBNZW1iZXJfNA--&NextRowKey=1%2112%21TmFtZV85ODE- HTTP/1.1
    Host: mystorageaccount.table.core.windows.net
    x-ms-version: 2014-02-14
    x-ms-date: Fri, 05 Sep 2014 05:49:19 GMT
    Authorization: SharedKey mystorageaccount:GD2w4pqsllzIOixNF/AfFqLkZhYzLpjK67a8OI7j6Go=
    Accept: application/atom+xml
    Accept-Charset: UTF-8
    DataServiceVersion: 3.0;NetFx
    MaxDataServiceVersion: 3.0;NetFx

Hi Kai Wu Toh;
As per the documentation here:
http://msdn.microsoft.com/library/azure/dd179428.aspx (2009-09-19 Shared Key Format Section, point #4), you would need to
convert all query parameters to lowercase. So your canonicalized resource string should be:
GET\n\n\nFri, 05 Sep 2014 03:57:11 GMT\n/mystorageaccount/mytablename\nnextpartitionkey:1!20!UmFjZSBNZW1iZXJfNA--\nnextrowkey:1!12!TmFtZV85ODE-
Give it a try. let me know if you still have further queries.
Warm regards
