Set file name returned from ASP.NET page by URL

[pawel]

Hi!
I have an .aspx page which returns an image. This page takes some GET
parameters, so URL looks like this:
http://localhost/page.aspx?id=1234
Now, when the user click this link, I want that his browser would receive
picture with some good looking name, like image1.jpg.
How to do this within ASP.NET code ?..

Write an HTTPHandler. Using the Handler, you can make a request for an image
file and get back whatever the handler returns. For example,

http://localhost/image1.jpg?id=1234

would return an image named "image1.jpg" - which could be anything you
generate via your Handler.

Thanks for the answer.
Can you shortly tell me what exactly is that HTTPHandler ?.. I cant find
such topic in MSDN.

You might try something like this:

Response.Clear();
Response.AddHeader("Content-Disposition","inline;filename=image1.jpg");
Response.WriteFile("myfile.jpg");

Sure. An HttpHandler is a class that handles HTTP requests. In ASP.Net a
Page class, for example, is the default HttpHandler for files with a .aspx
extension. You can map different file extensions to different HttpHandlers
in ASP.Net. What happens is, when the web server receives a request for a
file, it looks in its configuration to find out whether a special
HttpHandler has been designated for that file extension. ASP.Net provides
the HttpHandler class to extend the functionality of ASP.net to be able to
handle requests for other file types (extensions). In IIS, you make ASP.Net
the HttpHandler for the type of file that you desire, and use the web.config
file for your web to identify what DLL (Class Library) is used to handle
specific file extensions.

The HttpHandler is a clsss that handles the request. It has access to the
same HttpContext (Request, Response, Cookies, Session, Application, Server,
etc) that the Page class does.
