pdf render to asp.net web page results in static title

Question

having a slight issue where i am rendering a pdf (stored as a byte array) into an asp.net web page, using the code below:

Response.ClearContent();
Response.Appen         


        

Answer 1

Your headblock is being cleared by:

Response.ClearContent();

So even if you're setting it in , you're never sending that to the client.

Given the content type is application/pdf the browser doesn't know how to render the title, so it renders the URL.

Obscurity isn't a form of security, and if you're relying on the user not knowing the Url to prevent them from downloading the file again, you need to rethink. With a network inspection tool they'll easily be able to see which resources they're requesting, even if you do obfuscate the Url.
