C# ASP.Net Request.ServerVariables
Blog Date 18th May 2021
The Code
Request.ServerVariables("remote_addr")
Request.ServerVariables("http_referer")
Request.ServerVariables("http_user_agent")
And also useful
Request.Url.ToString()
The Explanation
Just the basics here. There are a lot more items that C# and ASP.Net can get from the request side including cookies.
remote_addr - The IP address of the machine that is asking for the web page
http_referer - The link that sent the user to your page. Often this is empty because either the user typed the address in the address bar or it's a spider so this info isn't given or there's some tricks to stop links being tracked back
http_user_agent - This is given by the browser. The idea is to provide the server with some details of the browser in case the server wants to format for certain browsers. Seldom correct, seldom useful, try your best to create code, in particular HTML, that works on (nearly) all browsers.
Request.Url.ToString() - The web address that was asked for. Basically the contents of the address bar in the browser.
