You will need to submit your completed assignments to the instructor within a password protected directory. Here is mine: use login/password metrprof/tooeasy to access files in my secret directory.
This directory secret is contained within the htmlex.tar, which was offered for download in the first part of the tutorial. See the file readme within that directory.
There are a bunch of tutorials out there: try google with .htaccess password protected directory.
Here is one that has some appropriate advice for SoM (exceptions will be listed following):
If your are doing this for credit, please send bfiedler@ou.edu the URL and
password for your password protected directory after you have it working.
The User Name for Dr. Fiedler should be metrprof.
As you complete
your tasks, or if you need help with partially completed
tasks, I can check your work with your privacy maintained.
