Thank you for clarifying this for me. Indeed, it works and works very nicely. I was able to integrate it without any problem. If you would permit me to ask one more related question, I would also like to know how to how to check for the end of HTML content. With your help, I am able read in all of the GET headers. I am still having difficulty reading in the HTML response since it the program doesn't know when it has reached the end of the HTML stream. (I am making a very simple PROXY server). Is there a control character that I can check for at the end of an HTML transfer? Forgive me for asking all of these questions, but I have had a hard time finding any useful documentation on IO::Socket. Thanks for reading this and for your previous help and have a nice day.

To do the fetching side of the proxy, you probably should use LWP. It'll save you from knowing about Content-Length, for starters (and therein lies the answer to your question). Search for that in the spec I linked earlier.
