CirrostratusAlso, you can get the 'Operation not supported' from trying to insert (and possibly remove?) HTTP headers on the same request that you have or will redirect from an iRule. The simplest fix might be to combine all of the iRules into one and only do the header removal and insert if you're not going to redirect the request. Or you could configure a custom HTTP profile with the header to erase as X-Forwarded-For, the header to insert set as X-Forwarded-For: [IP::client_addr] and then remove both XFF iRules from the VIP. This should be more efficient and avoid the iRule error.
