I installed and configured IIS (6.0) to use with my domino-server (6.50). This works great, the user is logged in automatically based on their windows username and password.
But… ;o)
For notesdocuments with a large attachments (ex 185MB), it returns the message “Internet Explorer was not able to open this Internet site. The required site is either unavailable or cannot be found”. (almost immediate)
I already tried to make changes to the “plugin-cfg.xml” - ResponseChunkSize. But no success.
Subject: IIS and large attachments - The requested site is either unavailable or cannot be found
On a previous project, the way we worked around some Domino behind IIS limitations was to do the following:
Set up Web SSO on the Domino server.
Configure Domino behind IIS with Windows SSO
Map the default page for your URL to a redirect page with the native Domino port referenced.
That should let you authenticate the user from with Windows credentials, give them a Domino web SSO token, and then redirect them to native Domino with a SSO token so that they don’t have to log in again.
It won’t necessarily solve all your problems, but it will allow you to simplify the troubleshooting at the point of the upload because the user will be using native Domino.
