Domino and IIS: A few gotchas
A quick post on a headache….
So we are setting up our test environment that will have Domino providing web services from behind IIS using the WAS plugin. The thinking is that we can provide secure services with no additional logins. Since the Lotus documentation on this configuration is lacking, I had used some community provided instructions. All looked good except when we tried to use impersonation from the .NET application, the results of the service call took 14 seconds every time. I placed some console timestamp prints in the code and it showed me that Domino got the request immediately, and the code finished within a second, but IIS would not return the results to the client for 14 seconds. When I connected directly to the Domino HTTP stack, it worked fine.
In a nutshell, use the WAS version 5 plug-in whenever you can. You can find configuration instructions at the Lotus Developer Domain (hat tip to Don Merritt).
