Is there any way or trick to open some database resource that resides on ServerB by sending the request to the HTTP task running on ServerA?
Of course, both servers are in the same org, and have proper access rights...
Creating a db link on ServerA that points to the db on ServerB works fine.
From the Domino Administrator this is not possible. So, on ServerA create a text file in the data directory (or a sub directory of that), fill it up with
ServerB/Domain!!Path\DBName.nsf and rename it to
http://ServerA/mydbname.nsf is requested,
Path\DBName.nsf will get served from ServerB over NRPC to ServerA, then HTTP will hand it to the browser.
