515171 - Some websites return HTTP 501 error if the UA is 'rm'

Status: RESOLVED FIXED

(Tech Evangelism Graveyard :: Other, defect)

Description

[Staś Małolepszy :stas]

When the user agent string indicates 'rm' as browser's locale, some websites do not work properly. They return 501 Not Implemented or 404. Examples:
http://stadt-zuerich.ch/
http://www.opensourcecms.com/demo/1/10/CMS_Made_Simple

Possibly related are these pages not loading their CSS:
http://www.eisenwerk.ch/
http://ckeditor.com/fckeditor-old-site

Our Romansh localizer, Gion-Andri, provides more details:
> I've found two types off errors:
> -first, some pages show an error when visiting with the romansh firefox:
> Method Not Implemented
> GET to / not supported.
> This are pages like
> http://stadt-zuerich.ch/
> http://www.opensourcecms.com/demo/1/10/CMS_Made_Simple
> 
> -second, there are pages that show error messages and no css styles. like
> http://www.eisenwerk.ch/
> http://ckeditor.com/fckeditor-old-site
> 
> I don't know exactly if it's the same error.

Filing this under Mozilla Localizations for initial triage.

Moving over to tech evang.

I contacted Stadt Zuerich for now.

If this happens on multiple sites, we'll need specific TE bugs for each site.

Did you receive an answer from Stadt Zuerich? 

Another example is also the newspaper WOZ

FWIW, on a few, I tested "rm-CH", no help. I also tested "ls", same issue, but "cat" is fine.

FWIW, "id" have same issue. Actually it's bug in modsecurity installation on Apache webserver, see https://www.modsecurity.org/tracker/browse/CORERULES-26 and http://ewesewes.web.id/2009/11/28/firefox-indonesia-and-http-error-501/

This issue seems resolved in newer modsecurity versions. Closing this.
