in thread "Action" variables and form data

Yet another example of why not to roll your own.

First of all you assumed that the query string only has one name/value pair. What if it has more? Use a hash? Well what if there are multiple name/value pairs? What if someone for testing turns a post back into a get to collect a URL and then wonders why their code broke?

Plus did you consider the poor schmuck who will use your code with form data that has been modified in escaping? At least you warned people that you got the first wrong. But you should also be pointing people to URI::Escape so they can decode the data.

No, it is far better to do as CGI intentionally does and leave get/post transparent within the CGI so that the developer can easily switch, and just use hidden form elements as they were intended rather than trying to mix and match.
