[sqlmap-users] Need some matching help

[nein w. <nei...@gm...>]

Ahoy. Having a problem here couldn't think of any other place to ask for
help so here I am.

A couple days ago I was using sqlmap to verify a potential injection I had
found earlier and was able to do some of the different enumerations
successfully (current-user, current-db, etc).

Anyway, the developers of said application came back in a day and said all
the problems on the site were fixed (mmhmmm). Turns out all they did was
remove the custom error page and instead now return a completely blank page
with a Content-Length of zero. There are obviously no strings to match since
there is no content...

Basically is there a way to do regex/str matching on the response headers?
Drawing a blank... maybe there are some other options that would fulfill my
needs that I'm not seeing?

Thanks.
