Some websites' urls have elements hashed in base64

[zhinu]

When trying to findout the location of the user sometimes it is found in the url.

However Ubereats has the address of the user hashed into the url.

I.e.

https://www.ubereats.com/fr/feed?pl=JTdCJTIyYWRkcmVzcyUyMiUzQSUyMkFtaWVucyUyMiUyQyUyM[…]OS44OTQwNjclMkMlMjJsb25naXR1ZGUlMjIlM0EyLjI5NTc1MyU3RA%3D%3D

we can extract what is located after pl=

JTdCJTIyYWRkcmVzcyUyMiUzQSUyMkFtaWVucyUyMiUyQyUyMnJlZmVyZW5jZSUyMiUzQSUyMkNoSUpDM2FMMXhPRTUwY1I0Q0JpZ1Q3eENnUSUyMiUyQyUyMnJlZmVyZW5jZVR5cGUlMjIlM0ElMjJnb29nbGVfcGxhY2VzJTIyJTJDJTIybGF0aXR1ZGUlMjIlM0E0OS44OTQwNjclMkMlMjJsb25naXR1ZGUlMjIlM0EyLjI5NTc1MyU3RA%3D%3D
