I am running the squid on my proxy server and provide proxy service to visitors. I want to add some HTML codes such as "<h1>Hi [USERNAME], you are useing my proxy</h1>" at the first line inside the <body> tag. And return this to my visitors. So they can not only see the page they want to, but also my notification. How could squid do that? I do some search, but find nothing. Thank a lot for any reply.
