I understand the security concerns associated with backticks. But using LWP modules is so slow it takes 3 days to check the links on this site. I also used the head and get binaries associated with libwww-perl but they are slow as well. I am using head to speed up the process. However, when this fails, I need to use get, excluding the contents. But even that is time-consuming. However, when using wget, it runs like a breeze. wget is already installed on the client's machine and comes with RedHat. HTTP::MHTTP sounds like it has a lot of potential. However, it requires installing libghttp. I just want to use the most efficient (and of course, safest) way possible. At this stage, it seems that wget/curl are the best applications optimized for this task. Please correct me if I am wrong. Thank you again.
