short url for SERVER

[pawan]

I have tried it both ways.

that is without creating any sub-domain and any DNS for admin

When I create the sub-domain admin for example.com and adding admin in dns A records for example.com
I am getting the home page of example.com instead of being redirected to http://server1.example.com:8080

Please tell me what I am missing.

Some Times not getting the full answer or hand-holding does help.

I was successful after digging in and trying various options.

I am putting it here, if it can help somebody out there.

to achieve admin.example.com redirect to server1.example.com:8080

I tried various options like:
Just putting the code provide earlier by Till in apache directive under option tab for website example.com

RewriteCond %{HTTP_HOST}   ^admin.example.com [NC]
RewriteRule ^/(.*)         http://server1.example.com:8080/ [L,R]

which was giving me error - page not found.

Then I created subdomain admin in website options and also added A record for admin in DNS record for example.com.

The result : I start getting the home page of example.com - no redirect.

Finally I deleted the sub-domain created in website options, deleted the DNS entry admin in example.com. I also deleted the code inserted in apache directive.

Than I created one new domain under :// domain option admin.example.com and created DNS records for admin.example.com.

I also created website for admin.example.com and in redirect option I inserted the full path like http://server1.example.com:8080 and in redirect type I selected [R,L] and

Presto - my-redirection was working perfectly.

I also checked the vhost file admin.example.com, where the code was automatically inserted in /etc/apache2/sited-enabled/admin.example.com.vhost file similar to given by till

 RewriteEngine on
    RewriteCond %{HTTP_HOST}   ^admin.example.com [NC]
    RewriteRule   ^/(.*)$ http://server1.example.com:8080/$1  [R,L]

Yes there was one more problem I was facing that I was not able to access server1.example.com:8080 or even server1.example.com from other PC than server.
Than I have added server1 to DNS record of example.com, which enable me to access the server1.example.com:8080 from anywhere.

Hope this will help someone in same situation.
