using forward: within uri configuration

[MASallum]

Describe the bug
Please provide details of the problem, including the version of Spring Cloud that you
are using.

When updating to Spring Cloud 2022.0.3 from 2022.0.0 I started to encounter a weird behavior by Spring Cloud Gateway. Currently, we are hosting a static html content within the public folder of Gateway project. It was working perfectly, however, after the upgrade to Spring Cloud 2022.0.3 it seems an infinte loop occur when I try to route to the following configuration:

spring:
  main:
    web-application-type: reactive
  cloud:
    gateway:
      routes:
        - id: portal
          uri: "forward:/index.html"
          predicates:
            - Path=/portal/**

Sample
If possible, please provide a test case or sample application that reproduces
the problem. This makes it much easier for us to diagnose the problem and to verify that
we have fixed it.

1- set up your spring cloud application.yml file with the following:

spring:
  main:
    web-application-type: reactive
  cloud:
    gateway:
      routes:
        - id: portal
          uri: "forward:/index.html"
          predicates:
            - Path=/portal/**

2- Host any index.html within your public folder ..

3- try to route to it, it will keep throwing errors for infinite time ..
