Cisco :: Configure SNMP Traps For Port 80 On ASA 5510?

Is there a way to send an SNMP trap form the ASA when port 80 is trying to be accessed??

We use the ASA5510 and also use ScanSafe Web Security. Web Security is great but we find ourselves worrying if user has edited their Browser connection settings to remove the proxy settings that we push down using Group Policy. We also cut off the users ability to make changes to those settings but it interferes when I need to troubleshoot a special program that cant use a proxy server. It just makes it harder for me. The other thing is that Group Policy only works for IE. Google Chrome will inherit the system settings in IE.  So we have Safari and Firefox as well as a lot of others to worry about not getting the configuration. There is also debate about limitting the use of anything but IE and FireFox.
 
Without laying down the law and getting all sorts of hate mail and death threats I would like to run ScanSafe in such a way as to make sure each user receives the Group Policy settings and that is all.
 
I would now like to just set up an SNMP trap on the ASA for ANY traffic that is trying to get to port 80. Either get in in my syslog server or have the asa email me directly. Scansafe sends the Internet traffic out on 8080 to the Proxy towers.
 
I could block port 80 outbound but again, I limit my ability to troubleshoot on the fly. I would have to break this every time I need to troubleshoot.
