SetEnvIf Host www\.domain\.com MAGE_RUN_TYPE=website
SetEnvIf Host ^domain\.com MAGE_RUN_CODE=domain_com
SetEnvIf Host ^domain\.com MAGE_RUN_TYPE=website

NOT WORKING

SetEnvIf Host www\.sub\.domain\.com MAGE_RUN_CODE=domain_com 
SetEnvIf Host www\.sub\.domain\.com MAGE_RUN_TYPE=website
SetEnvIf Host ^sub\.domain\.com MAGE_RUN_CODE=domain_com

Why is it so??? Is there any problem in my code? mod_env is enabled

Hi Abdulhakkim,

Were you able to figure this out ?

I too am facing a similar issue on Magento 1.9.2.4 CE
