Hi Mike,
Sure, Here I am sharing the solution to all of you guys.
For those who want to redirect without the encrypted link, Here is the solution.
If you need to redirect a link URL with a different link URL for Experience A & B.
Experience A: www.example.com/a
Experience B: www.example.com/b
Don't use the below-mentioned method on the A/B testing activity for redirection.

This will work, but you will get redirected with an encrypted link after the original domain as mentioned below:
http://www.example.com?mboxSession=67ee511f0aa54f77b9f2b509e7b763eb&adobe_mc_sdid=SDID%3D7F316783 4415BC85-25F09354020D0A74%7CMCORGID%3D2C488785558BC9F67F000101%40AdobeOrg%7CTS%3D157138104 0&adobe_mc_ref=https%3A%2F%2F
This looks like pishing,
Even if you uncheck the "Include Current Query Parameters" too it's not going to work.

Try this method: Click the plus symbol on the "Modifications" menu which is on the right side of the experience activity.

Select the "Modifications" and the screen will look like the image attached below:

Select the Modification Type: you will get 3 options to choose from.
Select the "Custom Code" section from the Modification Type:

Replace the link URL with your Experience B link URL. Click save!

That's it, guys. you're ready to redirect the Experience B without the encrypted mbox session-id after the original link URL.
if you face any issues please let me know...
