Why is Chrome calling the autocompleted url before validation?

Question

I\'m using an API on my website to send emails to the users and while testing my call I noticed I was receiving the email twice.

So the url looks like \"localh

Answer 1

This is Google's prefetch feature, which loads the page quicker, assuming you execute the auto-completed URL.

You can disable this option in Google Chrome:

Settings > Advanced Settings > Privacy: (uncheck) Prefetch resources..

Answer 2

Update 2019

I came across a similar question on superuser, which I provided an updated answer for.
