Brett when I use wget (by the way thanks for pointing out that tool), this is what I get. First without the proxy server: % /usr/local/wget/bin/wget -S --proxy=off http://www.someserver.com/webpage.html --10:08:01-- http://www.someserver.com/webpage.html => `webpage.html' Resolving www.someserver.com... done.

Other than the first line, all the lines have a colon. So I am not sure what is going wrong here. Any ideas? John
