simple iRule failing with IE 7.0

That sounds like you might be encountering a bug. Or perhaps IE7 is sending requests in a way that BIG-IP isn't handling correctly. Either way, you could probably contact support for help isolating the cause of the issue as it appears there might be a bug.

 

 

Does every request always hang when using IE7? Can you make identical requests in IE6 without encountering the failure? Can you mix and match the conditional checks you're performing in the rule to find out if it's one particular test that is causing the hang? Maybe try creating a test virtual server and use a rule with just one of the tests at a time. If you can't repro the issue, then try adding in more checks to see when it starts to fail.

 

 

Support would probably want to see tcpdumps on each VLAN the traffic is passing over to see if it is in fact the BIG-IP that's breaking the connections.

 

 

A couple of minor suggestions on improving the rule:

 

 

It doesn't look like you need to be using matches_regex to see if the user-agent contains the string "wget". You can use 'contains' for a more efficient test.

 

 

Also, you could add all of the URI comparisons to a class and then use "one of" to perform the comparisons. Click here for an example of using a class.
