When you use HTTP Transport through Transaction Integrator (TI) in Microsoft Host Integration Server 2010 to communicate with an IBM mainframe, you may experience the following issues:
Issue 1 occurs because the Transaction Integrator incorrectly includes the input data length for the TI application as the COMMAREA length in the HTTP header.
Issue 2 occurs because the Transaction Integrator was updated to use the underlying network transport to send the HTTP header. The underlying network transport sends the initial HTTP request, but does not include the Authentication field, in order to determine the supported authentication types on the remote system (HTTP server). When Transaction Integrator receives the response from the remote system, it uses a support authentication type to resend the HTTP request. This behavior is by design.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
After you apply the hotfix, Transaction Integrator includes the correct COMMAREA length in the HTTP request. The COMMAREA length indicates how much data will be returned by the mainframe application with which the Transaction Integrator application is communicating.
In addition, the Transaction Integrator HTTP transport is updated to set the PreAuthenticate property to True. This enables the HTTP header to include the Authentication property in the HTTP header on all HTTP requests to the same URI after the initial HTTP request is sent without the Authentication property. For more information about the PreAuthenticate property, refer to the following MSDN article :
