NSErrorDomain for packaging a HTTP result code?

Ther开发者_高级运维e is NSPOSIXErrorDomain for packaging posix errors, NSOSStatusErrorDomain for packaging Carbon errors, etc, etc.

Is there a standard domain for packaging an HTTP status code as an error?

id error = [NSError errorWithDomain: @"HTTP"
                               code: 404
                           userInfo: theInfo];

I know I could create my own error domain constant just by specifying my own string there, but that seems the wrong way to handle this. Surely there's a domain intended for this specific purpose?

I'm using NSURLErrorDomain for that purpose.

In the interests of closing this, I'm going to just declare that there isn't. If someone knows of a way, feel free to post another answer and I'll select it.
