[sqlmap-users] A thought about boolean based injection

[<du...@al...>]

So, I came to think about this scenario, and I haven't been able to 
really get it to work with sqlmap.

You have a page where, when injecting something like ?someparam=1' AND 
1='1 gives you the "normal expected page" (like a news article or 
something).
And ?someparam=1' AND 1='2 gives you the exact same page, but with an 
extra line of text saying something (like an error or a debug message 
for example).

So, the first one would give

"This is a news message"

While the second, false statement, would give

"[Debug, something went wrong, blabla etc]
This is a news message"


How would I go about getting sqlmap to recognize that as a regular 
boolean based injection?
It can use a time based injection in this case, but I want it to see 
the other alternative as well, as I know it is there.

Is this somehow possible?
