I inherited a site a while ago which has the following architecture..
www.thesite.co.uk <- the main homepage & info stuff
www.sharedsslurl.com/domain/catalog/ <- Online catalog
I took over after this was setup & took over population of the online catalog.
Now I am redesigning the homepage to be tableless CSS, xhtml. I use PHP to generate the site & mod-rewrite to provide friendly URLs
I have just created a rewrite rule so that links to the catalog from the main page use friendly URLs so the link
goes to www.sharedsslurl.com/domain/catalog/medical/sterilization.html
Obviously the browser shows the sharedssl url when it lands on the page.
Now for some Questions...
1) How do search engines index the rewritten URLs? - ie would they be listed in google as www.thesite.co.uk/medical/sterilization.html or www.sharedsslurl.com/domain/catalog/medical/sterilization.html
2) can I use a rewrite rule on the sharedssl domain (assuming it is correctly set up) so that www.sharedsslurl.com/domain/catalog/medical/sterilization.html is displayed as www.thesite.co.uk/medical/sterilization.html?
I suspect it is not possible to do No 2. but would welcome any thoughts...
I think ideally for SEO the bulk of the catalog should be on the main site url & only the checkout pages on the SSL domain - and will probably aim to move to that at some point in the future.
