Place an entry in the Tomcat log when a user logs in to Web-Cat showing their username and IP address.
As an instructor, I give hands-on laboratory exams and would like students to use Web-CAT to test
their submission. An obvious shortcoming for exam situations is that students can share their
username/password thus allowing others to download their submission.
If their IP address was recorded when they logged in, I could monitor submissions by
checking if one username is logged in from multiple IP addresses.
