Description

Hi. It seems that lighttpd won't handle numeric tlds. Tried with bot numeric+alpha eand pure numeric tlds.

Yes, numeric tlds aren't part of actual ICANN's TLD's, but anyway, as of ICANN'S applicant book (Draft V3 of october 2009), numeric and pure numeric TLD's are not a problem. Pure numeric tlds should however append a non-numeric subdomain in their tld policies if the tld is somewhat between 0-255.
Also, it seems that numerous of numeric and alphanumeric TLD's are in approach for 2010 ICANN gTLD's evaluation. Oh, and we just can't use lighttpd in our company due to these restriction. Sticking with Apache here.

Excuse the wrong GET requests. Here is a relevant example :

What is the reason Lighttpd checks the TLD?

Because its rfc-compliant, you´d be the first whining if not.

Does the HTTP RFC require you to return a HTTP error if the hostname doesn't follow RFC rules?

After a quick read, HTTP RFC does not seem to require this check.

Disabling the check is pretty simple (see quick'n'dirty attached patch), more interesting solution could be to modify the logic of the check in order to not detect a host with numeric TLD as an IP address

Updated by stbuehler over 13 years ago

Target version changed from 1.4.29 to 1.4.x

I someone provides a sane patch to use a less restrict check for hostnames given that a new config option is set, i will apply it.
apart from that i think numeric dns labels are just wrong (especially numeric tlds).

btw: the http rfc links to other rfcs.
