Redirect Website using DNS
Hey guys,
We need to redirect a public website (say for ex. yahoo.com) to a different website. I tried doing this via CNAME record in my 2008 DNS server but it didnt seem to work right. Any help?

Hello
You can't do that in that way. The Cname can be used as an alias for a web site (ex you type yaho and your browser go to www.yahoo.com)
If you want to filter things you need a proxy server, like ISA server.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
with a CNAME (or alternate A RR) you can impersonate a site. The server needs to understand the hostname sent to it as the name that is typed by the user...
so if you want to handle yahoo.com then with something like
yahoo.com CNAME yourserver.com
then yourserver needs to be able to handle yahoo.com (as yahoo.com is mentioned in the http request).
To capture the information in transit you need to setup a transparant proxy (so the browser doesn't (need to) know there is a proxy)
squid can help, but needs something that will redirect traffic through it.

if the alternate DNS record don't work, check if you use a proxy ... because then the proxy resolves the ip to the name and often the proxy points to external dns-servers ...

thanks guys! in the HOSTS file can i redirect a website to a local file path on my pc?
say localhost\server\testwebpa
say localhost\server\testwebpa
The host file can be loaded before all DNS research. So you can say:
www.yahoo.com 10.0.0.1
where 10.0.0.1 is the IP adresse of your internet server.
But this file can be edited by all admin users, unles a GPO rewrite the correct version on each reboot.

The hosts file doesn't redirect either, it does what DNS does: points a name at an IP address.
The server on the other side must be willing to answer the request for whatever name you originally use.
If that's what you intend then it'd be best going back to your question, what about it didn't work right?

your webserver also needs to be configured to accept any name or your example of yahoo.com
In case to your own pc use the address 127.0.0.1

NO, this is not so simple.
While you call http://externalservername/file.html for the a file at a webserver your local filesystem dont answer to http:// . a Redirect to file://localhost/file.html
You Need a local webserver, and a local dns overwrite (via Hosts-file) to Redirect the request to your local ressource.
But if your browser uses a Proxy, the local name-Resolution is not used.

Do you have a web server you can bounce the request through?
