simple:   gets a small html file   gets a small gif file   gets a small html file (depends on alternate port number)epipe:   client closes connection (generates broken pipe in proxy)   gets a small html file (to make sure server is still running)tcpread:   sends request in small chunks - makes sure proxy prepared to   get the request no matter how much arrives at once.    stress:    repeats 250 times: get small HTML file, get small image filegarbage:   1. sends request with invalid method    2. sends silly request - echos the response (should be an HTTP error)   3. sends request with NULL in URI   for all of these the script sends everything that comes back from the   proxy to STDOUT - there should be HTTP errors. post:   2 requests, the first one is a small post, the second is a little larger.
