right , we change the original url so we can use the fasthttp internal functionality

probably we should change this back

maybe you can support us with a pull request and a unittest for it

this should be separated into 2 issues maybe.

[ReneWerner87]

feel free to create a pull request with the solution for both things

@ReneWerner87 I think we need to reopen this issue. If I try the code snippet mentioned in the comment , I can still reproduce the bug. Try hitting the /index endpoint twice.
i gave a fix for this in the PR
