This is the "logical AND" operator from Boolean algebra, not the period used
to separate parts of a filename (or URL, which is a type of filename), and
therefore not relevant to the current thread.

I had to work with OS/360 filenames using periods starting in 1969.
Unfortunately memory fails to serve when trying to recall what we called
those periods.  I can't recall if "dot" was used.  I seem to recall that some
people used "point" but I cannot remember if that were the dominant usage.
