Handle the httpmodule in iis

Question

If you see the yahoo site, when you enter www.yahoo.com, the yahoo server gets your IP, and redirects you to the specific domain (yahoo.ca,yahoo.us,....)

Now, I want do this,Not for special site, I want to get any request send to iis (www.1.com,www.2.com,www.3.com) and with the algorithm, redirect user to the new site for example:

 Request: www.1.com GO To -> www.yahoo.com
 Request: www.2.com GO To -> www.google.com
 ....

I want handle IIS, no each webconfig's site.

Can anybody help me?

Answer 1

In addition to Afshin's answer versus discovering a user's geographical location also look at this.

Unfortunately, a HTTP Module only works at the web site level; to do what you need you have to look at ISAPI_Filters.

See http://msdn.microsoft.com/en-us/library/ms972974.aspx for more information.

We ended up buying a product linked from that page; ISAPI Rewrite

implementing the IHttpModule you can do this, I've done the similar (not exactly) by following this guide:

and using this page you can find the source country of the request
