What I'm trying to do:
Display different different pages depending on the domain in HTTP Refer
Example:
1) Traffic from abc.com gets redirected to
http://www.mydomain.com/index-abc.html
2) Traffic from xyz.com gets redirected to
http://www.mydomain.com/index-zyx.html
3) Traffic from no referer (bookmark) gets redirected to
http://www.mydomain.com/index-bookmark.html
Also, the redirection should be invisible, i.e. the page contents will be of a different page but it will show as
http://www.mydomain.com/
