Found the answer.
Going to the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters and added two new DWORD (32bit) values MaxFieldLength and MaxRequestBytes
They need to be set to something larger than the defaults, in my case I used the maximum allowed values which are 65534 and 16777216 in Hexadecimal.
Then you need to restart he computer and voila.. problem solved.
