http://www.celebrazio.net/tech/unix/apache_bench.html Easy way to verify: Code: $ wget <url> Repeat that twice, then: Code: $ diff <retrieved filename> <retrieved filename>.1 See if there are differences. If yes, then you can ignore the length-related failures. If no, it's some other cause and need to investigate further.
