I found another way of doing this. If you want to access it from the same project it's is very easy.

Steps to use it in code behind

1. Basically it create a class with a class name.
2. You can create a object of that class.
3. Then you can call ProcessRequest.
4. It will execute that handler.

Suppose I have created a handler as follows

public class HandlerName : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
       //some code
    }
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

So you can use it as follows

HandlerName obj=new HandlerName();
obj.ProcessRequest(HttpContext);

Note that you can get the current context and you need to pass it in the process request. More about HttpContext ^{[1 2]}

Edit 1

You can also overload the ProcessRequest method in case if you need to do this.

public class HandlerName : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
      // some code
    }
    public void ProcessRequest(HttpContext context, string someString)
    {
       // do your coding here
    }
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

If you don't want to override the method the you can pass the values as follow
You can add the value in the HttpContext.Current.Items

HttpContext.Current.Items["ModuleInfo"] = "Custom Module Info"

and get it as follow in the ProcessRequest Method

public class HandlerName : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
      string contextData = (string)(HttpContext.Current.Items["ModuleInfo"]);
    }
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}
