+## Accessing Http request information example
+
+### Setup fission environment
+First you need to setup the fission according to your cluster setup as 
+specified here: https://github.com/fission/fission
+
+
+### Create the class to run
+
+Secondly you need to create a file /tmp/func.cs containing the following code:
+
+```
+using System;
+using Fission.DotNetCore.Api;
+
+public class FissionFunction
+{
+    public string Execute(FissionContext context){
+        var buffer = new System.Text.StringBuilder();
+        foreach(var header in context.Request.Headers){
+                buffer.AppendLine(header.Key);
+                foreach(var item in header.Value){
+                        buffer.AppendLine($"\t{item}");
+                }
+        }
+        buffer.AppendLine($"Url: {context.Request.Url}, method: {context.Request.Method}");
+        return buffer.ToString();
+    }
+}
+
+``` 
+### Run the example
+
+Lastly to run the example:
+
+```
+$ fission env create --name dotnet --image fission/dotnet-env
+
+$ fission function create --name httpinfo --env dotnet --code /tmp/func.cs
+
+$ fission route create --method GET --url /http_info --function httpinfo
+
+$ curl "http://$FISSION_ROUTER/http_info"
+Accept
+	*/*;q=1
+Host
+	fissionserver:8888
+User-Agent
+	curl/7.47.0
+Url: http://fissionserver:8888, method: GET
+
+```

 ## Developing/debugging the enviroment locally
 
 The easiest way to debug the environment is to open the directory in
