Andrés Tarasco send this ideas....
When taget servers have configured some responses to generate a 302
(redirection), and when URL is not specified on Location Header at
first, all pentesting process stops itself.
Can be very usefull to do --follow-redirects to perform more advanced
tests (for example, on searching pages).
Usefull to support some websites who have parameters sended by POST in
an AJAX request, but the website not reflect the modifications.
In this scenario is necesary to access to another URL to see if the
malformed parameters are working correctly on the injection or not.
Idea is try to automatice this checking process.
