Symptoms
Consider the following scenario:
-
You have a computer that is running Internet Information Services (IIS) 7.5 or IIS 8.0.
-
You create a custom request-level module that registers for the RQ_SEND_RESPONSE event notification. You register and enable this module in IIS.
Note By doing this, IIS calls the OnSendResponse method of the module when it sends the response buffer. -
A client request is sent to the computer, and the request is received by the ISAPI extension. Then, a response is returned.
In this scenario, IIS does not notify the modules that have registered for the RQ_SEND_RESPONSE event notification. Additionally, information about the event is not logged on the computer.
For example, RpcProxy.dll is an ISAPI extension that runs in IIS 7.5 or IIS 8.0 in a Microsoft Exchange environment that has Outlook Anywhere enabled. In this example, IIS 7.5 or IIS 8.0 does not log a "200" HTTP status code for successful client requests.Cause
This issue occurs because IIS does not notify the module if IIS initiates a send request directly to the http.sys file together with the disconnect flag.
