Customization

• Please replace the http://www.prio-soft.tk/ with your desired page URL.

Step 5 Finally hit the Save template

In the above code I have set my Blog home page URL and when a user press CTRL+U then s/he will be automatically redirect to My Blog homepage. Similarly if I add any other page URL then they will automatically redirected on that page. This is just like magic. I hope you would love this trick and apply on your Blog to protect your content.
