For any redirects that point outside of your FQDN, you need to use a special kind of DNS record called an HTTP Redirection record.
These records are actually an A record that points to a dedicated web server containing the 301 redirect to the external FQDN.
Types of Redirects:
There are different types of HTTP Redirection. Standard Redirection sends your domain visitors to any website you specify. The true address of the destination website – not your domain name – will display in the viewer’s browser.
Frame Masked (Hidden) Redirection sends your domain visitors to any website you specify, just like Standard Redirection, with one difference: the destination URL will be displayed in a framed HTML page. So your domain continues to display in your visitor’s browser when they reach the website and while visiting any page in that website.
Visitors can enter sub-directories after your domain. If you wish, you can disable this for your domain by opting to enable the “Hard Link” option. With “Hard Link” turned off, the user will be redirected to the final destination URL and nothing else the user may enter can change that.
URL Redirection can also be used as a simple fix if your ISP is blocking incoming port 80. First you want to create an A record that points to your IP. Let’s say we create one called ‘www2′. So for this example let’s say that the FQDN is www2.example-1.com. You will then need to find a port that your ISP is not blocking. For this example let’s say that the ISP is not blocking 8889. You will then need to configure your web server to accept requests on port 8889. You will then create an HTTP Redirection that will send all traffic for www.example-1.com to http://www2.example.com:8889. Now when a user types http://www.example-1.com they will be redirected to http://www2.example.com:8889.
How to Set Up HTTP Redirection Records
Step 1: Enter Managed DNS
At the top of the Control Panel, Click the DNS Menu and select Managed DNS from the drop down.
Step 2: Choose your domain
Select a domain from the either the Recently Updated Domains box, or start typing the domain name in the textbox on the “Select Domain” tab.
Step 3: Add the Record
Under HTTP Redirection Records click the plus sign to add a new record.
As an example, we will then add an HTTP Redirection record for www.example.com to http://www2.example.com:8889. The Title, Keywords and Description are only used if you choose the Frame Masked Redirection Type to define those attributes for the frame. When finished, click Submit.
Name: This will be the host for your domain which is actually a computer within your domain. Your domain name is automatically appended to your name. If you are trying to make a record for the system www.example.com. Then all you enter in the text box for the name value is www. Note: If you leave the name field blank it will default to be the record for your base domain. The record for your base domain is called the root record or apex record.
URL: This will be the destination URL (uniform resource locator) that our forwarding servers will send requests to.
Redirect Type: There are currently three options: Hidden Frame Masked, Standard 301, and Standard 302. Choosing the Hidden Frame Masked option under this field will cause the redirection to occur in a hidden iframe within the requesting user agent (for example, your clients web browser). For example, with Hidden Frame Masked set, an HTTP Redirection record with the name ‘www’ under the domain ‘example.com’ and a URL of ‘http://www.dnsmadeeasy.com/support/’ would cause the requesting user agent to continue displaying ‘http://www.example.com’ in the address bar even after redirection has occurred, as opposed to showing the URL that the requesting user agent was redirected to. Choosing the Standard 301 option under this field will cause the redirection to be done as an HTTP 301 Moved Permanently status. This informs the requesting user agent that this redirection is permanent (or long term). Choosing the Standard 302 option under this field will cause the redirection to be done as an HTTP 302 Moved Temporarily status. This informs the requesting user agent that this redirection should be considered temporary (or short term).
Title: (optional) If set, the hidden iframe that is used in conjunction with the Hidden Frame Masked Redirect Type will have the HTML meta description data field set to the value of this field.
Keywords: (optional) If set, the hidden iframe that is used in conjunction with the Hidden Frame Masked Redirect Type will have the HTML meta keywords data field set to the value of this field.
TTL: The TTL (Time to Live) is the amount of time your record will stay in cache on systems requesting your record (resolving name servers, browsers, etc.). The TTL is set in seconds, so 60 is one minute, 1800 is 30 minutes, etc.. Systems that have a static IP should usually have a TTL of 1800 or higher. Systems that have a dynamic IP should usually have a TTL of 1800 of less. The lower the TTL the more often a client will need to query the name servers for your host’s (record’s) IP address this will result in higher query traffic for your domain name. Where as a very high TTL can cause downtime when you need to switch your IPs quickly. Best Practice Tip If you plan on changing your IP you should set your TTL to a low value a few hours before you make the change. This way you won’t have any downtime during the change. Once your IP is changed you can always raise your TTL to a higher value again.
