I came across a great web development tool today. It is called post parrot. Post Parrot allows developers to send POST variables to the home page and it echos back what was in the post. It also show the client IP and headers that were sent.
I know most developers would create a view that printed out the request.POST but for super fast form testing or when you are testing a post that does not go to your own site, it is the bees knees.
When I was a super dummy and just learning php I tried to create a spider for a site that had no API, but did have a search form. Not knowing that I could look at the POST with fire bug (not sure it was even around then) I tried multiple times to send a POST to the search tool. I finally figured out that there was some hidden variables, but it was too late.. the site operator saw me as a bomber and blocked my IP. I wish I would have had Post Parrot back then.
