 * Hi,
 * I removed Google related URLs from the Prefetch DNS Requests since I installed
   CAOS and OMGF plugins in order to speed up my site. I also removed Google map
   from my contact page.
 * However, those URLs still shows up on page view source. I cleared all cache and
   can’t figure it out why it is still connecting to them. Please help.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fprefetch-dns-requests%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@sailors](https://wordpress.org/support/users/sailors/),
 * Can you please tell me which URLs are you exactly referring to?
 * Have you tried disabling your plugin and switching to default WP theme to see
   if those URLs are gone after that, and then try enabling them back one by one
   to see which one is causing the troubling URLs?
 * I suggest doing this test on a staging site or if you don’t have one make sure
   to have a full site backup ready before you perform the test on the live site.
 * Cheers,
    Predrag

 * Thank you for your reply. I had to disable all my caching when setting up CAOS
   and OMGF but didn’t know that so that was the reason I got weird behavior. It’s
   fine now.
