I think it would be helpful to get a clear idea of the symptoms of the problem before trying to use an iRule to change things. If you have a support contract, this is something F5 Support should be able to help you troubleshoot. It would be helpful to capture a tcpdump on all interfaces the traffic passes through on. Remove any iRules, enable a basic HTTP profile without caching/compression enabled. Try to capture a single TCP connection in one dump where it works (text isn't garbled), and another request which fails in a second tcpdump.

 

 

You can use a command like this to save a tcpdump trace to a binary file:

 

 

tcpdump -ni 0.0 -s0 -w/var/tmp/`hostname`.opera.broken.dmp host CLIENT_IP or host SERVER_IP

 

 

If you have multiple servers in the pool, you can either add them to the end of the tcpdump command using 'or host SERVER_IP_2', or you can disable them and just trace on one server IP.

 

 

If you do figure out an iRule is required, reply here and let us know.
