I'm working with a client who moved to a new domain just before we launched our SEO campaign. As part of his transition, he of course notified Google via Webmaster Tools. His site is a large forum-based site with all links in the form of:
He also had his tech team set up an http handler so that all inbound requests for the old domain were redirected to the same page on the new domain. Everything works great, but there was some discussion about whether or not this http handler is a suitable replacement for 301 redirects. I didn't know the answer, but thought I'd ask here. The site's content is sufficiently complex that I suspect 301s would be difficult to set up.
Pages are indexing just fine, rankings are moving up, and page rank from the old domain has carried over and is associated with the new domain. Seems like all is well, just want to be sure that we're not harming anything by not having created any 301s.
Any insight would be appreciated.
