If you are using Firefox Indonesian version and getting HTTP error 501 Not Implemented on some websites, here is an info.

The culprit lies on the modsecurity installation on Apache webserver. The rules are:

• For modsecurity 2.5.10 (tested), using Core ModSecurity Rule Set ver.2.0.3: Rule id 958885 on modsecurity_crs_40_generic_attacks.conf around line 253 (254?)
• For modsecurity 2.1.7 (tested) using Core ModSecurity Rule Set ver.1.5.1: Rule id 950006 on modsecurity_crs_40_generic_attacks.conf around line 105-108

Workarounds:

• For modsecurity 2.5.10, workaround is to disable rule id 958885 in file modsecurity_crs_40_generic_attacks.conf
• For modsecurity 2.1.7 with core rules ver 1.5.1, workaround is to remove string “id” on the regular expression of rule 950006 in file modsecurity_crs_40_generic_attacks.conf

Tested using:

• Web browser:
  • Firefox 3.6 (Localized version: Indonesia, nightly build) using following User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; id; rv:1.9.2b5pre) Gecko/20091126 Namoroka/3.6b5pre
  • Firefox 3.6 (Localized version: Indonesia) on other platforms (win32 and linux)
  • Released versions: Firefox 3.5, Firefox 3.0 (Localized version: Indonesia)
  • wget -U “Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; id)”.
• Webserver:
  • CentOS 5.4 on VirtualBox, using compiled Apache (2.2.14) and compiled Modsecurity (2.1.7)
  • Fedora 10 on VirtualBox, using Apache RPM (2.2.11-2.fc10) and Modsecurity RPM (2.5.10-2.fc10)

I’ve reported the bug to modsecurity.org: https://www.modsecurity.org/tracker/browse/CORERULES-26 (you will need a login to view)

Update: tajidyakub has dicussed this this thread a year ago.

Update 2: Fix the rule id in the workaround

FreSh Jumat malam kemarin adalah acara pertama saya sebagai anggota komunitas Mozilla untuk tampil sebagai pembicara. Topik yang saya presentasikan adalah tentang sekitar Mozilla Firefox Indonesia dalam hubungannya dengan penggunaan Bahasa Indonesia di Internet. Satu pertanyaan yang mengganjal di pikiran saya selama ini saya keluarkan: mengapa butuh Bahasa Inggris hanya untuk ber-Internet ria?

Tentu saja, menggunakan Bahasa Indonesia dalam perangkat lunak/gadget/situs web s*cks. Although it s*cks for you, maybe it won’t s*ck the other. If you don’t like it, don’t use it . Stop complaining, start to care for other Indonesian people, won’t you?. The web is not only for you, that’s all.

Terima kasih buat Ivan Lanin, Catur, Pitra, dkk. You guys rocks!

Update:

The report is here and here.

Aulia wonders something. What’s the irony actually? Is it just because the topics is about Indonesian language and the speakers doesn’t even bother to use Indonesian language in a right way?

There are 2 websites mentioned on Okto’s blog (hell yeah, I read those entries at Planet Terasi every day). And I also have take a look at another 2 websites, 2.0 slogan included or a tweet-like functionality expanded.

A friend of mine stares at me when I logon to Facebook with Indonesian user interface. She laughs when she saw my Facebook. You probably heard the term “unduh” lately. Why (not) Bahasa Indonesia?

This question is always popping out of my mind everytime I take a look for Indonesian websites. Is this a cost of <insert Microsoft Windows term here> monoculture (pirate version included) or we are just lazy using computer terms in Indonesian? How many of you installed Indonesian LIP for Windows XP or Vista?

My first highly unscientific guess is that English term is always shorter and we hear it everytime, we saw it everytime, so we use it everytime, and get stuck with it. Even now as early as elementary school. How many elementary students know what is “ponsel“? They call it using its “English” abbreviation, spelled in Indonesian way. Heck, even English people call it “cell phone” or “mobile”, people in Germany call them “handy“, and French are using “portable“.

And then another questions pop out. Are we:

• using English because the developer of the website is only know the common UI words for the website in English? (Home, Login, Search, Register, About Us, Back, Top, bla bla bla..)
• using English because the target user is the people that already familiar with English websites and using Bahasa Indonesia is just too weird, and make use of it will slowdown our speed to socialize?
• using English because we don’t really care who is the target user and we don’t really care as long as I got my job done
• using Bahasa Indonesia is not “cool” enough, doesn’t attract people?
• promoting English first, Indonesian second?

Why am I complaining?  I even wrote this in my poor English.
Maybe I’m OMDO, I don’t have any stat here, do I?
