Why do server error codes start at 1xx and not at 0xx. I know 1xx, 2xx etc. have their own meaning, but why doesn't it start at 0xx ?



I read most of the HTTP protocol and browsed trough the error codes without any luck.

  • This approach is something of a defense against bad implementers. Do you write out 50 or 050 for the relevant status code? If it was 50, is its first digit "5" or is it less than 100? Just starting at 100 avoids these questions (which aren't hard, but they're still a source of bugs).

According to the link that you provided:



"The first digit of the Status-Code defines the class of response. The last two digits do not have any categorization role. There are 5 values for the first digit"



There is no real reason for this and it's just a standard. As a design matter it's better to deal with fixed digits. The characters are fixed. It's clear and easy to understand. Also it says that it must be 3 digits. having 0 for the first digit complicates things easily.
