We're testing a secure (https/SSL) webwork setup on our test server, and have a coiuple of questions.
First, what fraction of webwork servers out there runs https? Are any breakdown numbers available?
Next, mostly everything in our test setup is working smoothly. One issue we found is when using the firefox browser, where accessing the main webwork page or a course login page, results in a "Connection not secure. Parts of this page are not secure (such as images)," warning message. The message appears when I click the padlock with exclamation mark in the URL - see screenshot. After logging in, the padlock turns green and all other pages has a green padlock displayed in the same place and no warning message. This behavior only occurs with firefox. The chromium browser does not show any warnings on any pages.) How can I fix this and avoid the firefox warnings? Is this because the main webwork page and the course login page contains some http-links? (It doesn't look so great when the login page to a site displays a "not secure" warning.)
Lastly, while mostly everything seems to test out smoothly, one time I accessed a homework set, the images were broken. Is there any risk that we may encounter issues with cached webwork images/formulas when runnig a https server?
