Custom Actions Based on URL

Question

I am developing a portal site that will serve as a resource for multiple companies.  Companies will create their own subdomain and redirect traffic to my shared websites IP address.

Based on the URL of the visitor, I'd like to display a custom image to the user (the logo of the company they are visiting)

How can I easily check the HTTP headers and update my Image control so that I can have logic based on the visitor URL.

Thank you

You'll need to call Application.DoEvents() before Thread.Sleep(), otherwise the color changes will be cached by GDI+ and won't take effect until the method ends.

Here's how I'd do it. I'm assuming that the buttons all have different colors to start with and you want them to retain their colors when they are in sorted order. You don't need to deal with the case i == 5 as it will never be called:

        public void SwapColor(Button b1, Button b2)

        {

            Color tempColor = b1.BackColor;

            b1.BackColor = b2.BackColor;

            b2.BackColor = tempColor;

        }

        public void BubbleSort(int[] array, int Size)

        {

            int temp;

            for (int pass = 1; pass < Size; pass++)

            {

                for (int i = 0; i < Size - pass; i++)

                {

                    if (array[i] > array[i + 1])

                    {

                        if (i == 0)

                        {

                            SwapColor(btn1, btn2);

                        }

                        if (i == 1)

                        {

                            SwapColor(btn2, btn3);                       

                        }

                        if (i == 2)

                        {

                            SwapColor(btn3, btn4);

                        }

                        if (i == 3)

                        {

                            SwapColor(btn4, btn5);

                        }

                        if (i == 4)

                        {

                            SwapColor(btn5, btn6);

                        }

                       

                        Application.DoEvents();

                        Thread.Sleep(1000); // 2000 is a bit long 

                        temp = array[i];

                        array[i] = array[i + 1];

                        array[i + 1] = temp;

                    }

                }

            }

            a();

        }
