Being a simple visible redirector, SA actually does detect it:
[7375] dbg: uri: cleaned html uri,
http://1092229727:9999/https-www.paypal.com/webscrr/index.php
[7375] dbg: uri: html domain, google.com
The problem is that SA doesn't then go on to do checks on the IP
1092229727 (CPE-65-26-26-95.kc.res.rr.com [65.26.26.95]) like it would
if it was in dotted-quad notation. Thus the hit on Sorbs' DUHL is avoided.
This is definitely a bug. Please open a bug report and attach a
complete sample to the bug.
