I'm setting up a win 2012 / IIS 8 web server with URL Rewrite module installed to replace an existing web server.
It will have 3 heavily used sites on it mapped to different domain names.
- domain1.com (site 1 in IIS with host name binding to domain1.com)
- domain2.com (site 2 in IIS with host name binding to domain2.com)
- domain3.com (site 3 in IIS with host name binding to domain3.com)
The problem I have is that I have many legacy domains (~20) that need to be redirected (301) variously to these sites and external sites.
1) I can use URL Rewrite rules defined at the server level to create these redirects
2) I can create an additional site, and use host name binding to bind all these 20 or so names to that site, and then within that site use - URL Rewrite rules
3) what else would be more efficient?
I'm kind of leaning towards option 2 because I would guess the site name bindings would be more efficient than evaluating the URL rewrite rules to all incoming requests - and the URL rewrite rules would only be evaluated when a matching host name came in. Looking at the existing logs traffic to the legacy URLs is < 1%
