[Virtuemart] Refused to set unsafe header "Connection"

While I was working on a Joomla 1.5.18, Virtuemart 1.1.4 website, I encounter this problem of "not able to add to cart" problem with Virtuemart.

When "Inspect Element" in Chrome, I got the following error
Refused to set unsafe header "Connection"
XMLHttpRequest cannot load Origin is not allowed by Access-Control-Allow-Origin.

Apparently, after debugging for a while, I found out that for Ajax calls, and are considered different domain, thus the considered as unsafe "Connection"


The solution for this is pretty straight forward - make sure you are at the correct domain. To do this, create/add the following code in the .htaccess file in your public_html directory.
RewriteEngine on
RewriteCond %{http_host} ^$ [nc]
RewriteRule ^(.*)$$1 [r=301,nc]
Note: Replace with your domain.

That is by far the easiest way to solve this issue.
