} Does squid use checksums to check if a file has been modified on the web
} server? If so, editing the file will change the checksum, and when squid
} goes to check if the file's changed, it'll come to the conclusion that it has.

No it does not - to calculate the checksum it would need to retreive the
file, which kind of defeats the object of If-Modified-Since cacheing! Its
done on dates alone. If HTTP returned some form of signature in the
header this would help.
