URL Redirection

The Redirect URL function in the control panel allows you to set up subdomains which forward to directories in your web space.

For example, you have a subdirectory called /project. You can use URL redirection to map the subdomain http://project.yourdomain.com/ to the files in this directory.

To do this requires two steps in the control panel:

Click on "modify URL redirections" and follow the instructions to set up a new subdomain.

Click on Modify DNS. This allows you to add entries to the zone file for your domain on our name servers. You must set up the same subdomain name with an A record pointing to the IP address given to you in the "modify URL redirections" section.

There are three ways to host multiple sites on one IIS server.

1) Using seperate IPs for each site.
2) using different ports.
3) using Host headers.

You are using Port method. In this method the client must know the port number to connect tothe site having assigned different port #, as the default port is 80. I think you don't want your clients to remember port # to connect to the site (81). But you can't redirect clients from IIS with Port method.

I would suggest you to use the 1st method os using seperaate IPs.

1)Assign additional IPs to the NIC card.(in TCPIP Protocol properties in Network Properties. & click Advanced.)

2)Then after restarting Pc. In IIS manager assign different IPs to each site in Web site Properties. (You'll see the IPs listed there.)

3)Then update your DNS server with the Host records for each site.
:)

Yes you can assign different addresses / IPs to a single IIS server.

1) Make sure to add the Host records in your DNS server.

2) Assign Host headers in IIS.

& Enjoy. :)

Easy and fast!
Bind another ip address to the nic card, define another site using this new address, (by setting up host headers)
Add a record to your DNS to match the new ip address.

Hope it helps!!
