This module is loaded by mod_http to handle generation and serving of friendlier HTTP error pages.

Option Type Default Description
http_errors_detailed boolean false Show detailed errors, eg tracebacks, which may aid in debugging.
http_errors_always_show boolean true Serve a page when the error does not have a detailed description
http_errors_default_message string "That's all I know." Default message when there's none for the current error code in http_errors_messages
http_errors_messages table See below Specify messages for various error codes

An example of http_errors_messages, showing the default strings, below:

http_errors_messages = {
  [400] = { "What kind of request do you call that??" };
  [403] = { "You're not allowed to do that." };
  [404] = { "Whatever you were looking for is not here. %";
    "Where did you put it?", "It's behind you.", "Keep looking." };
  [500] = { "% Check your error log for more info.";
    "Gremlins.", "It broke.", "Don't look at me." };

If the first string contains an percent (%) character, it gets substituted one of the later strings, picked at random.
