Sub Domain URL Redirect

[amulrajesh]

Dear All,

I have issues while rewrite cond checking for sub domains. i have a domain name example.com and sub domains csk.example.com and kfc.example.com.

Using godaddy i have pointing ip address with forward masking to sub domains.

Whenever i type csk.exmaple.com in url, the apache rewrite condition checks ip address instead of checking csk.example.com.

Here i have place my actual code and rewrite log

ServerName www.example.com
ServerAlias *.example.com
RewriteEngine on
RewriteLog /var/tlog/apachelog.txt
RewriteLogLevel 5
RewriteCond %{HTTP_HOST} ^(www\.)?(m\.)?([a-z0-9-]+\.)?example\.com [NC]

RewriteRule ^(/customer/)?(.*) $1 [L,QSA,PT]

On type http://csk.example.com/els/ re write log :::
