Can you please explain why this is needed? Feign isn't a proxy

[galaxy-sea]

hello @spencergibb , RestTemplate migrates to OpenFeign. RestTemplate provides org.springframework.cloud.loadbalancer.blocking.XForwardedHeadersTransforme, but OpenFeign does not provide XForwardedHeadersTransformer

[galaxy-sea]

Refer to RestTemplate and WebClient .

Check Set 'X-Forwarded-*' header when using loadbalanced RestTemplate issus, Don't know why OpenFeign doesn't provide support

hello @spencergibb , Please consider merging this PR

[galaxy-sea]

hello @OlgaMaciaszek , I have updated the document,

[galaxy-sea]

I think these documents should be placed in Spring Cloud Commons

[OlgaMaciaszek]

@galaxy-sea it is already documented there. But it's good to reiterate here, since we add the code separately (there's no full parity between the OF LB client and the Commons LB clients).

@OlgaMaciaszek, Thank you for unlocking my doubts
