Content-Disposition:What are the differences between “inline” and “attachment”?

October 3, 2022 by Tarik

Because when I use one or another I get a window prompt asking me to download the file for both of them. This behavior depends on the browser and the file you are trying to serve. With inline, the browser will try to open the file within the browser. For example, if you have a … Read more

When should I use OWIN Katana?

October 3, 2022 by Tarik

In asp.net WebApi v2, the OWIN pipeline becomes the default. It is eventually going to be the standard pipeline under any asp.net project. I cannot put it better than what is written here : http://www.asp.net/aspnet/overview/owin-and-katana/an-overview-of-project-katana The section “The Open Web Interface for .NET (OWIN)” explains perfectly the goals of OWIN. Without OWIN, the asp.net bits … Read more

By definition, the browser will make that via a GET request, even if the original request was a POST. … Read more

Response.Redirect simply sends a message (HTTP 302) down to the browser. Server.Transfer happens without the browser knowing anything, the browser request a page, but the server returns the content of another.

This has been driving me insane for the past few days and couldn’t get around it but have finally figured it out: In my machine.config file I had an entry under <system.web>: <deployment retail=”true” /> This seems to override any other customError settings that you have specified in a web.config file, so setting the above … Read more
