return a file, c#, asp.net

string filename = "myfile.typ";
string fileStr = "";
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
byte[] bytes = encoding.GetBytes(fileStr);
//or any other way to serialize your file

Response.Clear();
Response.ContentType = "application/ics;charset=utf-8";
//the general rule is (1) google (2) application/fileType (3) if is text then text/fileType
Response.AddHeader("content-disposition", "inline;filename=" + filename);
Response.BinaryWrite(bytes);
Response.End();
Response.Flush();

OverTheWire[.com] Natas Walkthrough - JUST HINT, NO SPOILERS

game portal: http://overthewire.org/wargames/natas/ PASSWORDS for each level are stored in /etc/natas_webpass/natasX I made this walkthrough for people like me, i needed some help, but didnt want the spoiler, so here i will give you all the information needed to pass each level, yet not the solution. For levels needed custom web request i made a different post for powershell and javascript  with how-to's, since is a piece of learning for itself, and also for those of us that play at work and have only powershell at their hands.
