RavenDB-1033 Fixing the problem that streaming was not working on IIS when compression was enabled. The problem was the usage of:
response.BufferOutput = false and Request.Filter together
The zLib exception was thrown but only when the response was closing. The applied fix allows to stream the response however at the end of the response method we have to turn on the buffering back to avoid response flushing and writing to already closed compression stream.
