Ok so I'm working on my .htaccess file... I already have my own error messages for 403 and 404... I know I probably need a 500 error, but I know I don't need to make error messages for all 21 types that I can put in my .htaccess file..
So most likely I need 401/403*/404*/500... is there any other types that you have seen that I may need to add to this?
*done already
Why wouldn't you list all of them on the RFC? It's like easter eggs, and people will flock to your site trying to read all error messages!
Anyway I'd go for 400, 301, 503, and possibly 509. And 200 :)
These are what I have to choose from
400-415
500-505
Well technically I could edit it directly, but meh easier to use the tool.
The relevant RFC chapter (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html). Although it lumps the errors in with the other valid status codes too.
