[Owasp-o2-platform] CAT.NET

It might very well be because it's scanning one file at the time. Can I 
have it scan them all at the same time from the O2 Cat.net scanner? I've 
used "Scan a dll or a precompiled website", and then dropped the web site 
folder into the left hand box. But when I hit the "scan all targets" 
button, it seems to analyse the two dlls seperately.

I put the project here: http://erlend.oftedal.no/blog/dropbox/ Basically 
it's just a simple page with one XSS directly in the code behind and one 
through an assembly.

Scripting is definitely interesting. In the long run I want to run the 
scanner as a part of the continuous integration so I can have new reports 
ready each morning, and maybe also parts some of the contents to hav it 
break the build if there are any serious issues.

Regarding the conversion, the names seem a bit weird. It says stack1 := 
stack1.{System.Web.HttpRequest}.getParams() I might just be me not 
understanding how this is to be used, but it would probably be easier to 
get an overview if "stack1" was replace with the class name or something a 
bit more contextual.

I haven't been able to bring up the visualization graphs. How do I do 

I have not yet manipulated the rules or looked at the .NET 4.0 version 
(I'm still on .NET 3.5).
