Hello all I am trying to crawl a forum thread where each page is incremented by
a value of 15. I will exemplify:

Page 1: <http://forums.fstdt.net/index.php?topic=55.0>
Page 2: <http://forums.fstdt.net/index.php?topic=55.15>
Page 3: <http://forums.fstdt.net/index.php?topic=55.30>

Problem is that httrack always strays from the thread into other threads. I
have tried using the following as scan rules:
+forums.fstdt.net/*topic=55*
+forums.fstdt.net/index.php?topic=55*

What am I doing wrong here?
