Hi there,
I have a site where users need to double-opt for a newsletter. When they click the Confirm link in their email, they are not taken to the page set as "redirect after confirmation" but see the signup form page again. At first I couldn't reproduce it but then I could by clicking the same link a second time. At that point, the account is already confirmed and DW shows the form and not the redirect page. The customer says they are clicking only once, so something else seems to be reading these links. I did some research and found that some mail security software can extract and visit links, therefore approving the account without the user actually consenting. (This reminds me of Chrome prefetching URLs years ago, thereby causing destructive actions like deleting things that were accessible over a GET rather than a post.)
Has anyone seen this before and is there a way to handle it? A POST would handle this in a browser but for email that's a different story.
