Bypass the DataReductionProxy for all POST requests

POST requests are non-dempotent, so clients using the Data Reduction Proxy (DRP) can often end up at an error page due to the fact that if the DRP has any problems connecting to the origin, DRP and the client will not be safely able to determine if the post successfully made it to the server. The impact of this change on data compression should be very limited, and it will improve the client's experience.
