[LON-CAPA-admin] Problem possibly involving "multiple attempts"?

[Mark Lucas]

Paul,

I can't give you specifics as to the exact failure modes, but a common
issue is students who muck up there system with spyware/malware.
Kazaa was a bad one early on for mucking with the requests under the
hood. Generally, though, this made it hard for students to even get
logged in.

One student reported "it will say "successful login"  but then nothing else will load and it won't let me access other parts of the site." Another said that the system "consistently freezes up, kicks me off, or doesn't allow me to submit an answer." The second later reported that "It seems that it has trouble registering every time I get an answer incorrect when it allows multiple attempts. The program is perfect when answers are correct, but when I get many chances it likes to freeze up."  I don't know if the first of the two noticed anything similar, but they were in the same class and doing similar assignments.

OTOH, I did a "grep -c " 302 " acc* " to see if the number of 302s was abnormally high, and it seemed to be pretty comparable for the current access_log and for past logs (compared to the number of lines in the logs), so I'm not particularly convinced that this had anything to do with the problems they were experiencing.
