[TYPO3-english] rlmp_language_detection extension problem with new languages

[PIT Solutions]

Hi lists,

I've a problem with rlmp_language_detection extension version 2.3.1. I am using Typo3 Ver. 4.7.10.
My problem is, I've two new languages in my website : swiss german (dh) and swiss french (fh). Browser language detection is not working for
these two languages.

Translation of languages working normally.

My language configuration is ;

# language configuration
page.config.linkVars = L
page.config.sys_language_uid = 6
page.config.language = de
page.config.locale_all = de_CH.utf8
page.config.sys_language_mode = content_fallback 

# english language
[globalVar = GP:L = 0]
page.config.sys_language_uid = 0
page.config.language = en
page.config.locale_all = en_GB.utf8
[global]

# swiss french language
[globalVar = GP:L = 10]
page.config.sys_language_uid = 10
page.config.language = fh
page.config.locale_all = fr_CH.utf8
[global]

And my rlmp language configuration is;

plugin.tx_rlmplanguagedetection_pi1 {
useOneTreeMethod = 1

cookieLifetime = 0
multipleTreesRootPages {
}
dontAddSchemeToURL = 0
languageGPVar = L
useLanguageAliases = 1
countryCodeToLanguageCode {

dk = da
cz = cs
ch = dh
us = en
}

limitToLanguages = 
includeLanguages = en,dh,fh
excludeLanguages =
dontBreakIfLanguageIsAlreadySelected = 1
dontBreakIfLastPageWasOnSite = 0
testOrder = browser,ip
dieAtEnd = 0
}
page.1 =< plugin.tx_rlmplanguagedetection_pi1

Is any thing is missing in my configurations ? Please suggest a solution.

Thanks & Regards,
Arun C
