V9 RC4: Content finder causing redirect to /account/accessdenied

[mattbrailsford]

Which exact Umbraco version are you using? For example: 8.13.1 - don't just write v8

Umbraco v9 RC4

Bug summary

Accessing a URL in Umbraco that gets handled by a content finder, the content finder successfully triggers and calls request.SetRedirect(url) and returns true, but the site is getting redirected to /account/accessdenied in some kind of infinite loop until the error The request filtering module is configured to deny a request where the query string is too long. is thrown.

Specifics

No response

Steps to reproduce

• Create a content finder that redirects to a parent node
• Register the content finder before ContentFinderByUrl
• Call a URL on the front end that gets handled by the content finder
• Response ends up in an infinite loop

Expected result / actual result

I'd expect to be redirected accordingly to the returned URL.
