I have here an example how I can use Fiddler to replay a submission on a web form. I isolate the exact HTTP request and I execute it again.
The server in this case is responding positively and it’s sending an email each time.
Replaying HTTP requests can be useful not only to receive a confirmation email back, but has other various utilities.
You can repeat (if there isn’t a protection blocking mechanism of course):
-creating a post on a forum
-creating a new thread
-sending reset password emails
Fiddler can be used to decrypt locally the HTTPS traffic, but for many types of spamming.
I use it successfully in some cases for Load Testing and when I overloaded the server I got error pages with sensitive information, so I found security issues in this way.ShareThis
