I want to build a basic web app for accessing images I cant access normally. It works like this: let's say this image is not accessible on my network:

https://i.redd.it/n6y3rbn3qfm01.jpg

I will make a request to my app like this:

mywebapp.azurewebsites.net/Home/Mirror?url=https://i.redd.it/n6y3rbn3qfm01.jpg

And the controller will download the image and show it without client having to access i.reddit domain.

I tried doing this but it had 2 problems: it directly returns the file as download instead of showing it as an image in page and it only worked on my computer, not on Azure.

public ActionResult Mirror(String url)
{
    ViewBag.Url = url;

    Stream rtn = null;
    HttpWebRequest aRequest = (HttpWebRequest)WebRequest.Create(url);
    HttpWebResponse aResponse = (HttpWebResponse)aRequest.GetResponse();
    rtn = aResponse.GetResponseStream();

    return File(rtn, "image/jpeg", "Image_1");
}

what happens on Azure? do you get any error mesages/codes? – Francesco B. Mar 18 '18 at 09:56
Try including a content type so the browser knows it's an image rather than just a generic file. – JohnLBevan Mar 18 '18 at 10:17
It just says An error occurred while processing your request – yigitserin Mar 18 '18 at 10:18
Or base64 encode it and return in a page: https://stackoverflow.com/questions/1207190/embedding-base64-images – JohnLBevan Mar 18 '18 at 10:19
I think problem is in getting the image from url in the first place. – yigitserin Mar 18 '18 at 10:37
