.htaccess重定向基于带有屏蔽原始基本URL的引用者

Question

I have a url http://a.bc.com which is pointed to the ip address xx.xx.x.xx which will open up http://www.example.com

Now I want to show some particular page like http://www.example.com/somedirectory/somepage/ if some one hits http://a.bc.com

But I want keep my original URL same followed by directory and page. Ex, http://a.bc.com/somedirectory/somepage/ I tried this .htaccess which is not working for me.

RewriteEngine On
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^http://a\.bc\.com
RewriteRule .* http://www.example.com/somedirectory/somepage/ [R=301,L]

Please help me with the .htaccess with masking original base URL

Answer 1

HTTP_HOST doesn't include PROTOCOL, so remove protocol part from RewriteCond:

RewriteCond %{HTTP_HOST} ^a\.bc\.com
RewriteCond %{REQUEST_URI} ^/$
RewriteRule .* /somedirectory/somepage/ [R=301,L]
