[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 http://www.example.com/index.php. Origin http://example.com is not allowed by Access-Control-Allow-Origin.

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

Solution

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} ^example.com$ [nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]
Note: Replace example.com with your domain.

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

[Azure Websites PHP] Cross Domain request results in blank response page after Preflight HTTP OPTIONS

THE PROBLEM I've deployed a REST API application ( CodeIgniter with Phil Sturgeon's Rest-Server library ) on Azure Websites. Although I've set the Access-Control-* header in my PHP application: header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: GET, POST, DELETE, OPTIONS'); header('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept'); (If you need a working test file, here's the gist for the test file) But Azure Websites server doesn't return the headers in response. And thus all requests to the server failed with the error message: Origin http://example.azurewebsites.net is not allowed by Access-Control-Allow-Origin.   In order to make sure there's no problem with my application, I've deployed the same code to Appfog.com . And as expected, the application works just fine. The same application d...

[Magento] Create Contact Form with Dynamic Recipient

-
There are many ways of creating contact forms to email to multiple recipient. I'm going to describe a way that uses Javascript a the frontend to change the target recipient. Advantage of this method: Easy to add in new emails in the future. Disadvantage of this method: For those who are particularly concern email privacy, you might not want to use this method. You can modify the email checking to the backend (controller) instead. Okay enough talking, lets get started. Step 1: Set up HTML form fields I'm going to use an example of drop down select to change the email. Of course, this is fairly easy to modify with other forms as well. Open up app/design/frontend/default/<theme>/template/contacts/contacts.phtml Insert the following snippets anywhere between the <form>...</form> tag. <select name="interest" id="interest" title="<?php echo Mage::helper('contacts')->__('Please select department t...
