RegEx matching bug in redirect rules for your search results.

Fernandez

I only found this bug exists when matching reddit URLs, which is really weird.

regex: ^https?:\/\/www\.reddit\.com(.*)
replacement: https://old.reddit.com$1

The regex & replacement is absolutely CORRECT, we can verify it on https://regex101.com/

But this is the result:

Original URL:
www.reddit.com/r/palemoon/comments/o0og9f/arkenfox_userjs_usage_in_palemoon
Redirected URL:
old.reddit.comr/palemoon/comments/o0og9f/arkenfox_userjs_usage_in_palemoon/

The / before r is missed.

The correct redirected URL should be:
old.reddit.com/r/palemoon/comments/o0og9f/arkenfox_userjs_usage_in_palemoon/

I have no idea what is happening here.
Every other RegEx redirection rules works perfect, except this one for reddit.

Hi Fernandez,

I can confirm this issue - it seems to be something because of something deliberate that we do, but I couldn't tell you what for exactly 😃

In the meantime, for this rule to work correctly, you can append the leading slash of the match that gets removed: https://old.reddit.com/$1

We'll look into it further and see if the original can be made to work; I think it should be fine.

z64 Okay. If you will fix this, that's fine.
Just for your information, I find the RegEx has some problem with twitter URLs.

^https?:\/\/twitter.com\/([A-Za-z_][\w]+)(\/status\/(\d+))?.*
https://nitter.net/$1$2

For example link:
Kagi will redirect it to: https://twitter.com/examplestatus/123, the / before status is missing.

It seems the same issue with the reddit one.

Hope you will fix it soon 😁
