At work, we're trying to determine the effectiveness of domain collapsing for SEO purposes. Our current structure is to have multiple web apps served from different servers, such as
PUBLIC URLS - directly accessed by users www1.somecompany.com/webapp1 www2.somecompany.com/webapp2 www3.somecompany.com/webapp3
I'm proposing to put an Apache proxy in front of these applications that will mask the different domains and route the requests to proper server
PUBLIC URL--------routed/forwarded to-----PRIVATE URL www.somecompany.com/webapp1 <-----> www1.somecompany.com/webapp1 www.somecompany.com/webapp2 <-----> www2.somecompany.com/webapp2 www.somecompany.com/webapp3 <-----> www3.somecompany.com/webapp3
In terms of SEO/page rank value, does this help?
