SSR causes 302 redirects to normalized URL #33053

Command
serve

Description
Previously someone pointed out that SSR causes lots of 302 redirects (#31881).
The fix landed in #31883 but we are still facing the similar issue for other URL patterns.
I expect that Angular server returns 200 OK and then URL normalization happens solely on the client side.

This seems like a bug but we'll need to look at a reproduction to find and fix the problem. Can you setup a minimal repro please?
You can read here why this is needed. A good way to make a minimal repro is to create a new app via
ng new repro-appand adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

Hi @alan-agius4 ,
I created a minimal repro for this issue: https://github.com/kon72/angular-ssr-redirect-repro
All four requests should result in 302 redirect. (This is curl with HEAD method for brevity, but the same happens with browser requests.)
