# “http://mydomain.com” vs. “http://www.mydomain.com”

 * On a site that I created, I have an iframe that loads a WordPress blog. This 
   iframe expands based on the content in the blog. When I use “http://mydomain.
   com” everything works correctly but when using “http://www.mydomain.com” the 
   iframe doesn’t expand. I tried resetting the Permalinks but that didn’t have 
   any effect. Any help would be appreciated.

 * Thank you all for your replies and suggestions.
    I was able to fix the problem
   by editing the “Web.config” file on my window server and as it’s described [here](https://www.bigfin.com/blog/301-redirect-godaddy/).
