I concur, to the extent that phttpget[1] runs pretty much "blind". As it it, phttpget blindly accepts any 200 response, and drops any other response. What does this mean? Why would/could this be a problem? It slurps all 200 responses; meaning; if the response is not a file, but a web page asking for some kind of response from you, *that's* what phttpget downloads. It also means that if the 200 response is a web page indicating that the file you are looking for has moved, and has a link to it's new location. Then *that's* what phttpget downloads. The possibility's go on, and on. But you get the picture. :)
