Hi Romain!,

    I've been testing scalp with a log file that I got from a friend and
it's sending me lots of false positives, I'm reporting them, hoping that
you fix them in the 0.5 version =)

    ### Impact 5
    67.195.37.122 - - [04/Dec/2008:02:36:04 -0200] "GET

@andres

Scalp! alerts are based on PHPIDS.  If you find false positives please let them 
know
by posting this information to the PHPIDS filters forum:
http://forum.php-ids.org/?CategoryID=8

Thank you,
Don C. Weber

Ok, but in the PHP-IDS they'll tell me that it's a scalp problem :(

@cutawaysecurity:
It is absolutely possible that the problem is due to scalp. Even if the regexp 
are coming from the 
PHP-IDS project, there are some manipulation to do on the log lines in order to 
decrease the 
false-negative/positive.
Especially this part:
  http://code.google.com/p/apache-scalp/source/browse/branches/scalp-0.4.py#226

@andres:
Thanks for the report, I will look at this when I have a bit more time. It 
looks like these are 
bad false-positive, these are simple GET content

Sorry about the confusion.

@romain
I apologize, I thought this was a no brainer.
