Dear Richard
thank you so much,
I have applied your code.
The following error appeared: Cannot access a closed Stream.
I edited this "using (var writer = new StreamWriter(modifiedResponseBody))"
to "using (var writer = new StreamWriter(modifiedResponseBody, Encoding.UTF8, -1, true))".
then The following error appeared: Response Content-Length mismatch: too many bytes written.
I added this "context.Response.ContentLength = modifiedResponseBody.Length;"
befor "await modifiedResponseBody.CopyToAsync(originalBodyStream);"

Now it is working fine.

thank you.

thank you I will read your example, for now just I need to return a new response what I can do, I believe that will be a simple tip

I make it a normal method, nothing happens
if you can help me I will be thankful
