"This webpage has a redirect loop" in Chrome but working fine on FF and IE?
I appears that you are trying to redirect to the correct SEO-friendly URL, e.g. if I go to test/39454-foo.html, it redirects me to test/39454-~tara-past-tense-clause.html.
You compare the requested URI to the expected one and redirect if they do not match.
However, there are multiple ways of writing the same URI. Some browsers may send ~ urlencoded and some may not, for example.
So you should canonicalize both URIs before comparing them.
Double-check the redirection settings on your server. Add-on domains should not include "www." when being added. Without this, this will solve the redirection problem.
