IE6 freezes due to *server* configuration

Question

Our web site (running Rails) freezes IE6 nearly every time. The same code, deployed on a different server, does not freeze IE6. Where and how should we start tracking this down?

Answer 1

You need to determine the difference between them, so I'd start out with the following:

curl -D first.headers -o first.body http://first.example.com
curl -D second.headers -o second.body http://second.example.com
diff -u first.headers second.headers
diff -u first.body second.body

Answer 2

1. Might be a communication problem. Try wireshark against the server that freezes and the server that doesn't freeze. Compare the results to see if there is a difference.

2. Narrow down the problem. Start cutting out code until IE6 doesn't freeze. Then you might be able to figure out exactly what is causing the problem.
