Security Warning

You may be prompted about a "Security Warning" (because I am using a self-signed certificate). To resolve this restriction you will need to go to the Control Panel in Windows (or System Preferences on Mac), open the settings for Java, go to the Security tab, and add this website ( to the Exception Site List. (On a Mac, you may still have to modify other settings to get this application to run.)


This program allows you to make HTTP conections to servers of your choice and see the responses that come back, including header information that you would not normally see if you were using a browser. Sometimes seeing the header information of an HTTP response can be very helpful in debugging something, or perhaps one is just curious about what type of web server a particular site is using (which you can generally tell from the "Server" header).
