I recently loaded a pair of Asa 5520s in a ha configuration. All rules VPNs and svc are working fine. Ever since the implementation users are complaining that websites are not loading correctly. The formatting is goofy and red x will appear over some pictures. If the user hits f5 the page comes up fine. The old firewall platform did not have this problem. All packet inspection and tie outs are default. Running 8.2(5). Any ideas? I have been troubleshooting with Cisco for days. This issue is very sporadic but seems to happen when the network is under load.
