How do I see a history of what I've POST-ed in Google Chrome?

Question

I just submitted a form that included a text box, in which I had written a quite long text. In another textbox, I filled in a date in the wrong format - and instead of getting an error message, the web site just acted as if my form submission was valid, except nothing was saved.

Is there any way to see the history of what has been POST-ed (in the current session, at least), from where I can recover my lost text?

Answer 1

I don't think Chrome (or any other browser, for that matter) saves a history of <textarea> (multiline input) contents.

If the form uses normal (non-Ajax) submission, and you haven't navigated away from the result page, there's a trick you can try: Open burp suite (the free version, of course), configure your browser to use localhost:8080 as a HTTP proxy, and press Refresh on the result page. The browser will ask you if you want to repeat the submission - which should then be captured in burp's "proxy" tab. (For unsecured HTTP, a packet sniffer such as Wireshark would work too.)
