ACE Module Cookie Parsing causes Reset Connection

Question

I am trying to upgrade my ACE Modules from A2(1.3) to A2(3.2) . Unfortunately, the cookie parsing breaks when there are illegal characters and causes a connection reset (RST) when there is an invalid cookie, but only on code later than A2(1.3).
The cookie in question is being passed by a third party so making them change the cookie is not necessarily do-able. The cookie has the following value:
Cookie:  CurrentUser={"UserKey":{"Key":"anonymous"},"LastUpdated":"10/13/2010 1:35:52 PM"}
We are using the following parameter map:
parameter-map type http CASE_PARAM
  case-insensitive
  persistence-rebalance
  set header-maxparse-length 20480
  length-exceed continue
On the older code, the request is passed on to the server.
Is there a setting similar to "length-exceed continue" that I can give the ACE to tell it to ignore cookies it cannot parse?

Answer 1

HTTP inspection is not enabled.
Did you mean adding a class-default to the policy-map?
Adding it to the policy-map does make it match the class-default. Unfortunately, cookie parse errors result in the inability to parse both the cookie and the host header as well. It seems that rather than just failing to parse the cookie and being unable to do sticky matching - it completely fails the entire header parsing.
Here's our setup:
rserver host test1
  ip address 192.168.1.101
  inservice
rserver host test2
   ip address 192.168.1.102
   inservice
rserver host test3
   ip address 192.168.1.103
   inservice
rserver host test4
   ip address 192.168.1.104
   inservice
serverfarm host auto
  probe HTTP-diagnostic
  rserver test1

  rserver test2
