[Modsecurity] Problem with robots.txt with header pattern matching "^$"

[Lezgin Bakircioglu]

Hi everybody, I have problem with a rule thats denying webcrawler to
index my pages.
I am using Debian 3.1 stable with apache2 and using the modsecurity
package from the debian repository with the gotroot rules.
Now, I have used modsecurity for 6 months now so I am still cind of new
to it.
I cant find the rule that is blocking the header pattern matching "^$".
Anybody that can help me? I have my mailbox in the modsecurity list from
2006-02 but nothing.

Anyway, how is it going with the 2.0 version?:)
