Unable to update response header within wrap_fn

I use this project to append csrf cookie in my response header within the middleware function, started from the example, but I found the function would fail to update the header, the code as below:

pub async fn append_csrf_token(req: ServiceRequest,  next: Next<impl MessageBody + 'static>) -> core::result::Result<ServiceResponse<impl MessageBody + 'static>, actix_web::error::Error> {
        let mut response = next.call(req).await?;
        let http_req = response.request();
        if let Ok(identity) = Identity::from_request(&http_req, &mut Payload::None).into_inner() {
             if let Ok(user_json) = identity.id() {
                 if let Ok(user) = serde_json::from_str::<UserIdentity>(&user_json) {
                     //generate csrf token based on user token
                     if let Some(protect_key) = http_req.app_data::<web::Data<SecVec<u8>>>() {
                         if let Ok(protect_key_array) = protect_key.clone().unsecure().try_into() {
                             if let Ok(csrf_token) = user.generate_new_csrf_cookie(protect_key_array, 600) {
                                 let http_header = response.headers_mut();
                                 //code crashed here.
                                 http_header.insert(
                                     HeaderName::from_static("XSRF-TOKEN"),
                                     HeaderValue::from_str(&csrf_token).unwrap(),
                                 );
                             } else {
                                 warn!("failed to generate csrf token in middleware")
                             }
                         }
                     }
                 }
             }
        }
        Ok(response)
    }

Dynamic redirecting

The docs show that you can do this

// redirects "/oh/hi/mark" to "/oh/bye/mark"
Redirect::new("/oh/hi/mark", "../../bye/mark");

A nice thing to be able to do would be would be more dynamic redirects.
Examples:

// redirects "/redirect/me/to/here" to "https://hello.com/me/to/here"
Redirect::new("/redirect", "https://hello.com/../../..")

// redirects "/redirectme/tohere" to https://hello.com/tohere"
Redirect::new("/redirectme", "https://hello.com/..")

// redirects /redirect/me/to/here to "https://hello.com/redirect/me/to/here"
Redirect::new("/redirectme", "https://hello.com/**")
