Is it possible create a role-based link?
I have an htm file created from Visio, which contains 3 pages. Group A people
can see all 3 pages, but Group B people can only view 2 pages out of 3.
I could make two separate htm files with one containing all 3 pages and the
other containing only 2. I could then set two different access control for those
two files.
Now I need to link both htm files to a section of a Visio diagram (in a Page
Viewer web part). Is it possible to select the link depends on the role: group A
people will get to the 3-page file, but group B people will be redirected to the
2-page file?

A custom web part should be able to do it. But without any programming, is it
possible?
