DNS Prefetch?

Hi,

It’s like preparing and pre-solveing DNS record before user actually access to that site.

For example , https://my-website.com has a link to https://your-website.com, so I can put “your-website.com” into DNS prefetch, so when people access https://my-website.com , it’s already solved DNS record to “your-website.com” to save DNS resolving time when it access to “your-website.com”

sorry i didn’t want to bump a month old topic.
so if my domain was https://www.example.com
should i put “example.com” in the dns prefetch? or is should i add both https://www.example.com and example.com? @qtwrk

cheers

Hi,

depends how your DNS set up , but generally these 2 domains are treated as 2 different/separated domain , so yes, better add them both.

does it have to have // before each domain listed?

cheers

Hi,

Yes, please make URL starts with //

Best regards

thank you!
