IE8 Compatibility Issue

Hoping the group can help me out with an issue i’m having, mainly with ie8 users. The site loads perfectly fine on all other browsers without using the www. However when a user enters the url without the www. in IE8 the page very briefly flashes before being redirected to a 404 error. The issue seems to only be happening on the homepage (i’ve fixed with a 301 redirect for the time being) and any blog posts.

For example the link https://ajaxtennisclub.org/atc/2012/11/23/ota-newsletter-octobernovember-issue/ works in all browsers except ie8. If i add www. to the link, the page displays without any issues in ie8.

A friend mentioned that there might be a line of code causing the url to repeat, which ie8 is detecting as an error. Any information folks could share on such issues would be greatly appreciated.

Thanks!
