To ensure optimal bandwidth, you can also verify that HTTP keep-alives are enabled. HTTP keep-alives are an optimizing feature that maintain a connection even after its initial request is complete. HTTP keep-alives are enabled by default but can be disabled by adding the AllowKeepAlives value entry to the Registry and setting its value to 0.
Keep-alives are enabled if AllowKeepAlives does not appear in the Registry or if it appears and is set to 1. The only reason to disable keep-alives is for testing or debugging, or if the vast majority of connections involve only one data request.
AllowKeepAlives is an optional entry that appears in the Registry only if it is added. If it has been added, it is located in:
HKEY_LOCAL_MACHINE\System
\CurrentControlSet
\Services
\Inetinfo
\Parameters
