Updating this thread to feature request. I am also reposting our Q&A as discussed in our private thread.
B: The request should send the entire body, even if it is larger the Content-Length. The way Burp Suite handles this is a good example.
I found the Rules you mentioned, and was able to make what I needed to test work, thank you for the tip.
I'm also curious, would Fiddler display the entire body of a response who's body is larger than its Content-Length header?
A: Fiddler Everywhere will show everything sent from the server, i.e. in the case you've described - it will show the whole body even when the Content-Length header is not correct.
Hello, I saw a few places online saying that there was an option under Composer settings to disable automatic correction of Content-Length. However, I do not see anything other than the 'Follow redirects automatically' checkbox. My testing requires that I send an invalid content length, please advise.
