I have a requirement of hosting about 150 internet-facing extranet-sites with MOSS 2007 with all different domain names. These names should be host-headers, so that minimum number of IP-addesses is needed. Some of the domain names should point to same site in order to access the same content, but with different language setting etc. I'm thinking about doing this with host-header site collections wich is almost perfect solution for the job, but is it possible to point more than one host-header to one site collection? If I could do that then I could make a custom redirection code to redirect to a proper subweb based on host-header and all the subwebs could access each others data, like this.. www.domain1.comwould direct tosite collection1/contentA and it'd look like www.domain1.com/contentA www.domain2.comwould direct tosite collection1/contentB and it'd look like www.domain2.com/contentB www.domain3.comwould direct tosite collection2/contentA and it'd look like www.domain3.com/contentA ... It would be also possible for me to make a different host-header site collection for each domain name and make some of them just to redirect to same place. So there would be some 'dummy' site collections, butif I simply do 'Response.Redirect' then the URL in browser changes and that is not wanted and 'Server.Transfer' cannot be made to an absolute URL. So, is it possible to point more than one host-header to one site collection? It seems that it's not possible.. Or is there another way to host more than hundred sites with different domain names with single MOSS farm (and point multiple URLs to one site)? -Jari

Just curious - did you figure out how to use more than one hostname per "hostheader" site collection? I would like this approach as well..

You should be able to achieve this using Alternate Access Mappings and adding external URLs to the AAM collection for the site colletion.
