heitml Simple Debugging Configuration

Configuration basically means that you tell heitml who is allowed to access your Web Site in Debugging Mode.

Note that Debugging Mode privileges should be carefully monitored, because of security concerns. Debugging output contains the names and values of all variables, as well as your Source Code in Pretty Printing Mode.

Of course, the other side of the issue is that Debugging messages are critical to the program development cycle. If you are a heitml programmer working on Web Pages for your Web Site, and you only see Production Mode error messages like "this page is currently offline", you would hardly have much of a clue as to where to start searching.

The default configuration of heitml allows Debugging Mode permission for anyone viewing the pages from the same computer (i.e. IP address) heitml is running on. In 90% of Web Applications Development situations this should be sufficient. Make sure, however, that you are not using a proxy server. (If so, switch it off, just for your own Web Site).

If you are running on a multi-user machine, be forewarned that everyone running his Browser on this machine shares the same IP address, thus allowing him Debug Mode permissions. Also, be careful running a proxy on this machine, because anyone accessing your Web Site through this proxy will also have Debugging Mode permission. If either one of the above cases applies to you, you need to read the information in the advanced configuration portion of the Production Mode page. Also refer to this page to obtain information on how to collect Debugging Data while operating in Production Mode.
