As mentioned in the title, I am stuck on this level.
I used this method so far, but without much success:
Use the Dev tools in Firefox, open the Network tab, pick a HTTP POST request, right click then Edit the request
Changed the Content-Length from 6 to 12
Changed the Body from last=0 to Score = 194175
Clicked on Send
I also saw b3.swf in the inspector (dev tools) but don’t really what to do with it.
Hello. I also feel quite close and appear to be on a similar path as the OP.
I was originally in Chrome Network tool and am now in Firefox network tool as it seemed like I couldnt edit the request in Chrome. I am able to see the b3.php?submit POST network item.
I am attempting to edit and resend the POST request changing the score value to the appropriate value in the request body. I see the new network request appear in the listing but nothing seems to happen on the page.
