Retrieve redirected URL from httpRequest

Hey Guys,

My application has a feature where you can download 3D assets from the web via a URL. To make the redemption process easier we made a shortcode system, with it we can add the provided shortcode to a static URL, this will then “redirect” to the full URL that has the file.

For example:

shortcode = ER2DEF
static URL = https://staticurl.com/

so above shortcode becomes https://staticurl.com/ER2DEF which redirects to the full URL with the file.

The issue however is that I actually want to retrieve the URL it has been redirected to, instead of the file itself (or both really if that’s possible)

Currently I make a httpRequest with the below code.

	if (url.IsEmpty())
	{
		UE_LOG(LogTemp, Warning, TEXT("Url is empty!"));
		return;
	}
	
#if ENGINE_MINOR_VERSION > 25
	TSharedRef<IHttpRequest, ESPMode::ThreadSafe> httpRequest = FHttpModule::Get().CreateRequest();
#else
	TSharedRef<IHttpRequest> httpRequest = FHttpModule::Get().CreateRequest();
#endif
	httpRequest->SetURL(url);
	httpRequest->OnProcessRequestComplete().BindLambda([](FHttpRequestPtr request, FHttpResponsePtr response, bool bSuccess, FUrlHttpResponse Completed)
		{
			FString fullUrl;
			if (bSuccess && response.IsValid())
			{
				fullUrl = response->GetContentAsString();				
			}

		Completed.ExecuteIfBound(fullUrl);
			
		}, completed);

	httpRequest->ProcessRequest();

And it works fine however as mentioned I actually need to retrieve the URL it has been redirected to. Is it possible to do so?
So far I haven’t been able to find a way.

Thank you in advance
