As John said .lc files are parsed by the server and only the output is visible to the browser. But I'm like you, when storing things like MySQL login credentials I'm nervous about saving them in plain text, even in a .lc file. So I take the extra step of storing the credentials in an encrypted form in a file separate from the .lc script that calls it. Then I have the .lc script read in and decrypt the login credentials before logging in to the MySQL server. It may be overkill and one extra step, but most hackers go for the low-hanging fruit. I figure this makes it harder, so the bad guys will just move on to other targets.

My $.02.
