Unable to Transform Location Header in Proxied Response

[dolenox]

Hi

I am attempting to transform the location response header after following the "Direct Forwarding" example, with the following code:

I can see from debugging that I am setting the new location here as expected. However, a fiddler trace of the e2e proxied request still has the original location on the response header.

Can someone provide guidance of where I am going wrong?

The headers have already been copied to HttpContext.Response.Headers, you need to modify the Location there.

That, or move the base.TransformResponseAsync call after your modification of the HttpResponseMessage headers.

Thank you both.
